As Edmonton Valve Prepares to Enjoy the Holidays…

Plan ahead to make sure you have all the parts you need

Edmonton Valve & Fitting will take a little time off for Christmas and to celebrate the arrival of 2015.

We'll be open for a half-day on December 24th and closed on December 25th and 26th. Similarly, we will work a half-day on New Year's Eve, and be closed on January 1st. This is also a time of year when Swagelok takes some days off, so please factor that into your plans when you order. Shipping will take a little longer around the holidays. Normal operations for Swagelok will resume on January 2nd.  

Of course, here in Edmonton we'll always make time for our customers if there's an emergency. If it is after-hours or on a day we are closed, call our office (780.437.0640) and follow the prompts. We will do our best to help you the best we can.

Feeling pressure?

The winter holidays can put people under a lot of pressure as they wrap up their work activities, buy presents and get everything ready to spend time with friends and family.  And talking of pressure, what better time for a quick review of pressure regulators?

Swagelok offers a variety of pressure regulators, but how do you know which one is right for the job? Find out here.

Not long ago we presented two ways to find the right size regulator for the job. The quick way is to answer the following five questions:

1. What do you want the regulator to do? Usually it will be to reduce pressure, but sometimes you'll want a back-pressure regulator.

2. What is the inlet and outlet pressure ranges?

3. Will you be running a gas or a liquid through it?

4. What is the operating temperature?

5. What is the flow requirement?

With those answers, you'll narrow down your choices from the Swagelok catalogue. The second method involves some math, which you can download here.

Grading on the curve

Regulators are designed to perform at their best within certain ranges of pressure and flow. When you graph it out, you get a flow curve. Learn how to read these charts and you'll have a good way to see whether a particular regulator is right for your needs.

Expert viewpoint

We've brought Swagelok Field Engineer Eric Kayla to Edmonton to conduct in-house training on regulators. Here's part of a session he gave to our account managers and customer service representatives. It included these 7 facts about regulators.

Watch out for the creep

"Creep" is an industry term for when outlet pressure rises even though a regulator's poppet is closed. Every regulator is susceptible to it. This post shows you how to prevent it.

Security blanket

Some fluids have to be kept away from air. That can be tricky in a storage tank, when the fluid level can rise or fall. One answer is to use a tank-blanketing regulator.

A special K

Swagelok's K Series regulators are designed for analytical instrumentation. The K refers to the original manufacturer, Kenmac, a British company that Swagelok acquired in 2003.

Go with the flow

Swagelok's high-flow regulators are in the RHPS Series. They come in flange sizes up to 4 inches. They're designed for applications in the chemical/petrochemical, oil and gas, power, biopharmaceutical, semiconductor, and alternative fuels industries.

If Santa didn't put any Swagelok regulators under your tree this year, you can always put them on your after-Christmas shopping list. We'll be back open on Dec. 27, ready to discuss all your needs. In the meantime, enjoy the holidays and Happy New Year!
