We'll Put It Together: Electropneumatic Custom Valves

Thu, Feb 15, 2018 @ 13:02 PM / by Alecia Robinson posted in Valves, Custom Solutions


A little bit of custom work can make a big difference getting components in place

Electropneumatic Actuator Assembly.jpg

Our Custom Solutions department can build actuator assemblies like the one pictured above to save you the need for in field assembly, find out more about our Custom Solutions capabilities below.

Custom Solutions

When we talk about Custom Solutions, it may sound like a process for creating complex systems of components. While we are glad to take on big projects, Custom Solutions can also mean taking care of some simple modifications here at Edmonton Valve & Fitting so that you don't have to do the work at your site.

Take a basic component such as our 40 Series one-piece instrumentation ball valve, or our 60 Series three-piece ball valve. The standard configuration comes with a nylon handle, but we also can supply you with pneumatic actuators for those applications when you don't want to (or can't) turn the valves off and on by hand.

There's yet another option by adding customer specified three-way solenoid valves to the actuator to create an electropneumatically actuated assembly. In operation, an electrical signal goes to the solenoid to switch on (or off) the air supply to the actuator.

Ready to use

What Custom Solutions means in this case is that we install the solenoid on the actuator, and deliver the finished assembly to you. All you have to do is tell us the specifics of what you need. Are you running 120 volt AC, or 24 volts DC? In an emergency, do you want the valves to default to an open or closed position? You may want a fail-closed configuration to shut down operations, but you might have a critical line that needs to stay open. We'll also ask you how much air pressure is available.

To start the conversation, all it takes is a note through our website or a quick call to call to 780.437.0640.

Calipers, Combs, And Guides Help Make Sense of Threads

Thu, Nov 09, 2017 @ 12:11 PM / by Alecia Robinson posted in Valves, Fittings, Measurement Devices


Scratching your head about threads? We have three tools that solve the mystery

  The Pipe and Tube Sizes board (pictured above) is at our back counter. Bring in your fittings and we can help determine the sizing.
  The thread pitch gauge is another tool we use to help with thread size - it's even available for purchase! To get more info on sizing, download the Thread and End Connection ID Guide PDF.

Can you tell the thread size and thread pitch on a component just by looking at it? Neither can we. That's why we have tools that eliminate the guesswork.

When you look at a thread, you'll see peaks (called crests) and valleys (called roots). The part in between the crest and the root is called the flank. The first thing you want to find out is whether the crests are all the same diameter. That would mean you have straight threads. So we get out our calipers and measure the first, fourth and last crests. If the measurements are the same, you have straight threads. If you get three different measurements, you have tapered threads.

There's another way to tell, provided that you are working with Swagelok parts. Other than standard NPT, Swagelok fittings are uniquely marked to indicate ISO tapered or ISO parallel threads.

Some people are surprised to learn that straight threads are not designed to seal on their own. They require a gasket, O-ring or some kind of metal-to-metal contact to finish the job.

Tapered threads are designed to seal as the mating threads are drawn together. In addition, some kind of sealant is necessary to prevent leaks. That's usually PTFE tape or a product such as SWAK.

Here comes the "pitch"

Next you need to know how close together the crests are. That's the pitch, usually expressed as the number of threads per inch.

Straight threads come in three standard kinds of measurements. The most common are SAE (Society of Automotive Engineers), ISO 228/1 (also known as British Standard Pipe Parallel), and metric. Tapered threads also have several standard forms of measurement: NPT (National Pipe Thread), ISO 7/1 (also known as British Standard Pipe), and metric.

The flanks can come in different angles, known as Whitworth, unified, or metric.

To discover the pitch, we use a thread comb, also known as a pitch gauge. It looks a bit like a pocketknife, but the blades have saw-tooth edges that fit into the thread roots. We simply try different blades until we find an exact match. Some fractional and metric thread forms are very similar, so we take the time to make sure it's a true fit.

You also can turn to the Swagelok Thread and End Connection Identification Guide, which you can download for free. It has all the terminology, thread ID reference tables, and step-by-step instructions for identifying threads.

Lastly, Edmonton Valve & Fitting has a board with various sizes of threads. If you come in with a part, we can see which sample it fits.

Obviously, the threads on two parts have to have the same size and type of threads if you want to connect them. But you don't have to guess. Check in with Edmonton Valve & Fitting and we'll work with you to get the right answer. Give us a call at 780.437.0640 or get in touch below.

What Are Swagelok's PFA Fittings All About?

Wed, Oct 25, 2017 @ 09:10 AM / by Adam Telenko posted in Tubing, Valves, Hoses, Fittings


PFA 1.jpgpfa 2.jpg

We have a full line of PFA fittings, valves, and tubing, to get your copy of these catalogues download them below.

PFA Catalogues

Swagelok carries a variety of materials for our fittings and tubing so selecting the correct one for the job can be daunting. We discussed some of the options in our blog on special alloys earlier this year but today we will further explore our PFA line of tubing and fittings.

PFA, or Perfluoroalkoxy, is a type of fluoropolymer. It has very similar properties as the more common polytetrafluoroethylene (PTFE) – also called Teflon.

PFA is generally used for plastic lab equipment because of its optical transparency, overall flexibility, and extreme resistance to chemical attack. PFA is also often used as tubing for handling critical or highly corrosive processes.

What to consider

You can use Teflon or metal fittings with Swagelok PFA tubing. Just remember using PFA fittings with PFA tubing you need to use a Swagelok groove cutting tool to 'groove' the tubing and achieve higher working pressures.

Some other important things to consider when selecting PFA tubing and fittings are the following:
  • An audible ‘click’ sound ensures tubing is properly inserted
  • 316 SS fittings can be used with PFA tubing
  • PFA Plug and Needle valves are available 

How to order

PFA part numbers are slightly different than Swagelok’s common tube fittings, for example:

  • PFA-420-1-4 for a 1/4" male connector
  • PFA-820-6 for a 1/2” tube union

But don't worry about memorizing part numbers, give your local Swagelok experts a call and we will be glad to help out.

A Look At Swagelok's Medium Pressure Valves

Wed, Sep 20, 2017 @ 09:09 AM / by Alecia Robinson posted in Valves


Good for demanding applications that don't require high-pressure components

F10 Series Valve.jpg

The F10 Series of valves can handle up to 10 000 psig, making it one of our most popular medium-pressure valves. Download the Medium- and High- Pressure Fittings Catalogue to find out about the various medium pressure valves we offer.

If we caught your interest in our medium-pressure fittings, chances are you'll also want to learn about Swagelok medium-pressure valves. We carry various types: needle valves, ball valves, relief valves, and double block and bleed valves.

In the oil and gas industry, this is often where you'll turn for demanding applications such as:

  • Oil and gas
  • Wellhead control panels
  • Hydraulic control panels
  • Grease injector units
  • Blowout preventers
  • Chemical injection skids

It's important to check pressure ratings, as there can be some overlap in the ranges as you move from low-pressure to medium-pressure to high-pressure components.

For example, our F10 Series forged-body needle valves are rated for working pressures of up to 10,000 psig (689 bar). Other medium-pressure valves may be rated for working pressures of up to 20,000 psig (1378 bar).

A closer look

A single blog post doesn't lend itself to listing all the details of each type of valve, so for today let's focus on the popular F10 Series needle valves. In addition to their pressure ratings, they also can handle temperatures of up to 204°C with PTFE packing, and up to 454°C with graphite packing.

We offer these needle valves in straight, angle, and oblique configurations. All have half-inch female NPT outlets.

The valves can stand up to pressure thanks to the forged body of F316 or F316L stainless steel. On request, Swagelok can also make them from carbon steel and 25Cr super duplex stainless. The stem threads are cold rolled for high strength and smooth operation. A stainless steel shroud protects the threads against dirt and dust.

Thanks to a two-piece knuckle, the needle won't rotate with the stem. The joint is located above the packing, protected from system media.

Every Swagelok F10 series valve assembly is factory tested hydrostatically. A shell test is performed at 1.5 times maximum rated working pressure, and a seat test is performed at 1.1 times maximum rated working pressure.

A few options

For extra safety, our F10 series valves can be ordered with anti-tamper handles and keys to reduce the risk of human error or tampering. We also offer a stainless steel round lockable handles that can lock the valve in any position (though it is available only on straight valves and angle-pattern valves).

We can tell you more about all our medium-pressure components if you'll give us a call at 780.437.0640 or contact us through our website.

Compact and Able to Handle Heat: The VB0451 Valve

Fri, Jun 02, 2017 @ 08:06 AM / by Alecia Robinson posted in Valves


Here's a new addition to our line of space-saving process interface valves


The latest addition to our double block and bleed lineup is the VB0451, pictured above. This metal-seated process interface valve allows for an extended temperature range and greater resistance to particulate containing liquids.

Block & Bleed Download

Over the years we've written about some of our space-saving process interface valves, from the VB03 and VB04 for ordinary service, to the VN01 for severe service.

There's one more member of the family worth mentioning, because it's a new addition to our inventory in the past year: the VB0451. It's a metal-seated process interface valve that offers an extended temperature range and greater resistance to particulate-containing liquids than standard process interface valves.

As with all of our process interface valves, the VB0451's compact size and reduced weight means that it takes up less space and requires less support structure. Because it's a single-valve unit, you can install it faster than the more traditional three-valve assembly for the same job. Having a single unit also means fewer leak points and less required maintenance.

Taking the heat

Beyond the basics, though, the VB04051 can stand up to high temperatures. Where the VB04 is rated up to only 204ºC, the VB0451 can handle temperatures up to 310ºC, and up to 280°C for duplex valve assemblies.

Swagelok tests every metal-seated process interface valve hydrostatically at the factory to a requirement of no visible leakage. A shell test is performed at 1.5 times maximum rated working pressure, and a seat test is performed at 1.1 times maximum rated working pressure. These valves are tough.

Swagelok also performs a low-pressure gas seat test, and fugitive emission testing is available on request. Metal-seated process interface valves for sour gas service are available as well.

Other features

The VB0451 valve features double block-and-bleed design in a compact ball/needle/ball configuration. The one-piece forged body is available in carbon steel, 316 stainless steel or Duplex stainless steel.

The process connections can be from half-inch to two-inch flanges, and the outlet valve is available as a flange or a half-inch female NPT connection.

A lockable handle is standard.

If you'd like to learn more, call Edmonton Valve & Fitting at 780-437-0640 or contact us through our website, and we'll be glad to answer your questions.

Fluid Distribution Headers Save Space And Time

Wed, May 03, 2017 @ 14:05 PM / by Alecia Robinson posted in Valves, Custom Solutions


Get the configuration you want and get it quickly from Edmonton Valve & Fitting


Fluid Distribution Headers are common components used in a variety of gas and liquid applications. Download a free copy of the the FDH catalogue one of the many preassembled subsystems available from Edmonton Valve & Fitting. 

When you have multiple fluid lines serving the same purpose, a fluid distribution header can be a great way to organize everything and save space. It has an inlet on one end, a drain on the other end, and multiple outlets on the sides. Typically, it has a main isolation valve and several outlets, each with its own isolation valve. For potentially wet gases, such as compressed air or steam, the header can be installed vertically with a drain valve at the bottom.  For liquid service, install it vertically, with the supply entering at the bottom and the top valve acting as a vent for removing trapped air or allowing air in for draining during maintenance.

Maybe you have a cleaning station where you need to handle a half-dozen cylinders at the same time. Maybe you need an instrument air header, or an LP steam header. Consider it any time you have multiple runs coming off the same input. Run the fluid in the opposite direction, and a fluid distribution header can serve as a collection manifold.

Two mounting brackets allow you to mount the header on an aluminum plate, a steel stand, or a piece of pipe.

Space and time

The compact design is only one advantage over trying to accomplish the same job with pipe or tubing and separate components. It also has fewer connection points, meaning less opportunity for a leak to appear.

Ordering a fluid distribution header from Edmonton Valve & Fitting also saves you a day of work putting all the parts together. Because we assemble fluid system components all the time, we have the tools and the expertise to do it right. We also test every fluid distribution header that we make with nitrogen at 250 psi, plus liquid leak detector. We can do hydro testing up to 1,000 psi if you like.

And the entire assembly comes under a single part number, making it easy to order.

Locally made

Swagelok's fluid distribution headers are available in 1-inch and 2-inch sizes. The 1-inch platform is good for working pressures up to 3,000 psi, while the 2-inch platform can handle up to 1,000 psi. The extruded manifold body design features squared sides that mount solidly and prevent twisting. It can be ordered with 2 to 16 branch outlets, with or without valves, so you can add ports as needed without welding.

You get two more advantages when you order a fluid distribution header from Edmonton Valve and fitting. First, we're happy to customize it for your particular needs. For instance, you can order the header with instrumentation ball valves, process ball valves, integral bonnet needle valves or plug valves. We can put the outlets all on one side, if you like, and fit it with a variety of connection types. We can join two headers to handle 18 lines.

The second advantage is that, because we assemble them right here in Edmonton, you can get them quickly. If you chose a standard configuration, we can turn it around in a few days. Tell us the details of what you need through our website or by calling 780-437-0640.

VN01: A Space-Saving Valve For Severe Service

Wed, Mar 29, 2017 @ 14:03 PM / by Alecia Robinson posted in Downloads, Valves


Simplified design means less weight, fewer leak paths and lower maintenance


The VN01 double block and bleed valve leans out processes previously required for the job. To find out more about the benefits of this space-saving valve follow the link below to get your copy of our VN01 quick look guide and Block & Bleed catalogue.

Block & Bleed Download 

Having the right tool for the job can relieve a lot of headaches. With Swagelok's VN01 process valve, you'll have save on space, save on weight, and still get top performance for at high temperatures and high pressures. The added capability is due to all-needle-valve construction.

The VN01 provides double block and bleed isolation for process piping, and is right at home in the petrochemical environment. You could get a double block and bleed option in a multi valve, but with the VN01 you have it in a single, lighter, compact unit with a single CRN number. A lighter unit means less strain on your piping system and a reduced need for structural support. That's especially important when you need to protect your components from vibration.

The simplified design means you also have fewer leak paths and reduced installation costs.

Yes, we have 'em

You may already be aware that these kinds of valves exist, but you may not realize that Swagelok makes them. And Edmonton Valve & Fitting has standard configurations in stock.

But if you want to explore your options, the VN01 valve has several. You can get it with a standard or 3/4-inch male NPT inlet, or a 3/4-inch pipe weld. For the outlet, you have a choice of a standard half-inch female NPT fitting, but other options are available including a flange. There also are optional gauge ports.

If you could benefit from a lighter, more compact double block and bleed isolation valve, contact us through our website or by calling 780-437-0640. We'll be glad to give you more details.

Sometimes Stainless Isn't Enough

Wed, Mar 15, 2017 @ 10:03 AM / by Tristian McCallion posted in local expert, Valves, Fittings


Special Alloys are used in unique applications where stainless steel cannot hold up to the corrosive material.

Special Alloys.png

Swagelok carries an array of special alloys to meet our customers requirements, to find out more about special alloy uses download our Special Alloy catalogue.

How many materials can you get Swagelok tube fittings in? Two? Five?  Would you believe that our standard material list includes 16 different materials from nylon to titanium?

316 stainless is our most common material and is good for 95% of applications in northern Alberta but there are some limitations.

Special alloys

In the SAGD world on the water treatment side, there is often an elevated chlorine level in the boiler water.  Chlorine and stainless steels don’t mix well and it is common to find stress corrosion cracking in applications that have high chloride levels and stainless steel fittings and tubing.  There are a number of other materials that we offer that can provide the necessary corrosion resistance in this type of application, like Monel, or our high temperature carbon steel.

This is just one application where we are able to help out with special alloys.  Some of the other materials that we can provide include:

Teflon and PFA:  PFA is the injection moldable version of Teflon.  These materials provide for excellent chemical resistance to a wide range of different fluids.  Water treatment facilities are large users of PFA and Teflon fittings.

Alloy 400, or Monel:  This is a high nickel alloy that has excellent resistance to corrosion in reducing environments with fluids like hydrochloric, sulfuric and hydrofluoric acids.  It is also a commonly referenced material when looking at NACE specs.

Inconel 625: A very corrosion resistant in oxidizing and reducing media.  It offers high strength and good ductility.  It also has very good performance in sour gas (NACE MR0175)

Hastelloys:  C-276, C-22, B-2 are some of the grades that you can find, with C-276 being one of the more common alloys we deal with locally in this range.  It offers excellent resistance to pitting and crevice corrosion and immunity to stress corrosion cracking.

Duplex stainless steels:  A number of different materials are available here: 2205, 2507 super duplex and even the excitingly named 2707 hyper duplex stainless.  Often seen in offshore applications these materials have higher strength than 316 stainless and may have better resistance to pitting, crevice and general corrosion.

Swagelok makes fittings, valves and other components out of a wide range of different materials and would be happy to work on your applications with you.

Our Special Alloy catalogue provides additional information on some of the special alloys offered by Swagelok.

Swagelok Flange Adapters Ease Transition from Pipe to Tubing

Fri, Feb 19, 2016 @ 14:02 PM / by Katie Reid posted in Tubing, Valves, Fittings


Simplify the design and save weight compared with threaded branch connections


Interested in more information on Swagelok's Flange Adapters? Download your copy of the Flange Adapter Catalogue.

When a fluid systems operator wants to get information such as pressure, temperature, and flow from a piping system, one common method is to use Thredolet® or Weldolet® branch connections. That strategy may get the job done, but the results can be complex and cumbersome. It's easy to wind up with a multitude of nipples, valves, and other threaded or welded components.

All that added weight is subject to vibrations from the process pipe, increasing the chance of a pipe break, resulting in potential for a dangerous gas leakage. Then production has to be shut down while someone makes repairs; this can make for a costly day at the office.

A better way

Swagelok's flange adapters and modular flanged valves make the job a lot easier. They provide a threadless, weldless transition from flanged pipe to tubing, reducing both the number of connections and the overall weight. They come in several configurations, including flat face, raised face RTJ and tongue-and-groove. They also have wrench flats to ease the assembly of tube fittings.

We were able to implement this type of solution recently for one of our customers, a large energy company that transports and distributes crude oil, natural gas, and other liquids. They had problems with a system of branch connections on a system under 1,440 psi, taking fluid from a process pipe to a pressure relief valve. The heavy assembly created intense vibration. Now, thanks to Swagelok, the customer has a simple, clean connection that takes up little space and doesn't add much weight to the system.

Does your fluid system need a simpler approach to branching off from your piping system? Let someone from our staff show you how to make it happen.

Customers Asked, Edmonton Valve Responded: the Steam Lance

Fri, Feb 05, 2016 @ 13:02 PM / by Katie Reid posted in Tubing, Valves, Custom Solutions


The original idea was good, but we keep finding ways to make it even better


The Steam Lance, pictured above, is an unique product that comes pre-assembled and ready to use & install at your site. For all the product's highlights and benefits, download the Steam Lance info sheet.

It started when a customer asked Swagelok for a new kind of product. It would be a device that could be hooked into a steam line and used to remove ice buildup on equipment without having to shut the system down. Workers in the field would not have to improvise a tool on the spot that may not meet safety standards and could cause preventable injuries.

The result was the Steam Lance. It consists of a piece of insulated tubing, heat-shrink boots to seal off the insulation, and a 60 series steam-rated ball valve at one end. It's an elegantly simple solution that's ready to use right out of the box. The customer can order it with a single part number and can operate it with confidence because it's 100 percent tested before it leaves our shop.

But wait, there's more

Now the scene shifts here to Edmonton. We liked the Steam Lance, and our customers did too.

"We use steam lances to clear plugged drain valves, clear plugged piping, and for melting ice hanging from outside structures," says one of our customers. "There really wasn't a good off-the-shelf solution that we were able to find. There were some steam-cleaning tools on the market, but they were heavy and awkward to use in tight areas. This particular Steam Lance, on the other hand, is the right weight and size for the job - and it is pressure rated.”

But we, as well as our customer, saw room for improvement. We added a 12-inch piece of insulated pipe upstream of the valve, giving the operator something to hold on to other than the steam hose itself. We also insulated the valve to further protect the operator.

The key reason for making these improvements was summarized by our customer when he said, “The safety piece was really important as several people had been burned while using home-built solutions.”

At Edmonton Valve & Fitting, we know steam, and we know how to deal with cold weather. Put us to work for you. Download a copy of the Steam Lance Information sheet.
