Swagelok Regulators for Alberta Manufacturing & Processing

K Series

Our K Series includes 17 pressure-reducing, back-pressure and specialty regulators. Variants are rated for max inlet pressure and control ranges up to 10,000 psig. Includes 25 µm inlet filter.

RHPS Series

RS and BS regulators have soft/hard seals for pressures of 1,015 psig and 10,150 psig respectively. Tank blanketing versions address contamination and vapors.

Regulator Assemblies

These assemblies offer popular configurations for single or dual stage gas bottle or in-line service with our top-performing K Series regulators. Many options and configurations available.

Filter Retainer Assemblies for K Series

These assemblies combine the "circlip" ring, mesh, and filter into one piece, enhancing seal integrity around the inlet port. NPT ports are machined to extra-strict standards.

KV Series

A removable heating element vaporizes liquids or preheats gasses to prevent condensation. Diaphragm or piston sensing. KEV regulators carry ATEX, IECEx, and CSA certifications.

RS/RSH Series

RS regulators are rated for up to 101,50 psig and -45°C to 80°C. Several ways to configure loading, sensing, and control mechanisms. Sizes ¼ to 2 in. with flanged or threaded connections.

Gas Panel (SGP)

Our modular panel ensures gas is delivered at the correct flow rate to the next stage of the system. Any part can be removed via a Swagelok connection, so the panel never needs to be removed.

BS Series

BS(H)4, BS(H)6, and BS(H)8 are spring-loaded back pressure regulators for high-pressure gases and liquids. The LPBS4, LPBS6, and LPBS8 series are designed for high sensitivity.

Changeover (SCO) Assembly

The automatic changeover system seamlessly switches from one gas source to another to ensure an uninterrupted supply. A changeover station allows for custom changeover set points.

KCM Series

A two-stage gas system maintains flow by switching sources when pressure falls below set levels. If both tanks dip below thresholds, it balances flow from both.

Point of Use (SPU) Assembly

These compact assemblies help ensure consistency and safe operation at gas point of use. Customize for top-to-bottom or bottom-to-top flow, mounting method, and more.

HF Series

Our high-flow manual gas regulators use a load spring and special pressure-sensing assembly for precise outlet control. Adjust the pressure by turning the handle.

Source Inlet Connection (SSI)

Receive a pre-assembled subsystem connecting high-pressure supply to your gas system. Includes cylinder links, tubing, hoses, filters, and possible vent/purge functions.

How Swagelok Regulators Work

A pressure regulator has a sensing element (piston or diaphragm) which, on one side, is subjected to a load force (FS) created by a spring (as shown here) or a gas pressure. On the other side, the sensing element is subject to the force (F) of the system fluid.

A pressure-reducing regulator reduces a pressure and keeps pressure as constant as possible while the inlet pressure and the flow may vary. This is accomplished by the fluid force (F) being equal to or slightly lower than load force (FS) causing the poppet to open.

A back-pressure regulator keeps inlet pressure below a set pressure. This means the regulator can either open in case of excess pressure or close when the pressure drops below a desired pressure. This is accomplished by the fluid force (F) being equal to or slightly lower than load force (FS) causing the poppet to close.

RS and RSH Regulator Design

Swagelok's RS series regulators feature various poppet designs, a choice of sensing types (diaphragm or piston), and seat and seal materials to accommodate a variety of pressure, temperature, and flow conditions. They feature spring-loaded pressure control, diaphragm or piston sensing mechanisms, red knob handle or screw adjustment, 316L stainless steel materials of construction for corrosion resistance, maximum inlet pressure ratings of 232 to 10 150 psig, and pressure control ranges of up to 0 to 10 150 psig.

The RSH series regulators are a high-pressure version of the RS series regulators, and the LRS and LPRS series are low pressure, high-accuracy versions of the RS series regulators. The RS series regulators are available with many options, including a variety of gauge connection configurations, self venting, internal filter, external feedback, antitamper, special cleaning to ASTM G93 Level C, and NACE MR0175/ ISO 15156-compliant models.

K Series Regulator Design

In Swagelok's K series regulators, fine-pitch threads enable precise spring adjustment with low torque. The all-metal diaphragm acts as the sensing mechanism between the inlet pressure and the range spring.

The convoluted, nonperforated design ensures greater sensitivity and longer life. A piston sensing mechanism can accommodate higher pressures. Turning the handle compresses the spring, pushing the poppet away from the seat and increasing outlet pressure.

A two-piece cap design provides linear load on the diaphragm seal when the cap ring is tightened, eliminating torque damage to the diaphragm during assembly. The poppet damper keeps the poppet aligned and reduces vibration and resonance. And since regulators are susceptible to damage from system particles, Swagelok pressure-reducing regulators include a removable 25 µm press fit filter.

Swagelok's K Series regulators are common in analytical instrumentation applications. Swagelok RHPS Series regulators are an excellent starting point for general gas pressure regulator needs. RHPS regulators feature a soft or hard seal for pressure demands up to 1,015 psig and 10,150 psig, respectively.

Generally speaking there are two main types of regulators: Pressure-reducing regulators, which reduce a high pressure to a low pressure. This is usually what people have in mind when they think of pressure regulators. And back-pressure regulators, which control an upstream pressure. These regulators are very often used when a minimum upstream needs to be maintained through a system or where very fine overpressure control is needed. This video covers key concepts:

At Swagelok Edmonton we typically ask some combination of five basic questions:

What type of regulator are you going to be using? Usually it will be a pressure-reducing regulator or a back-pressure regulator.
What is the inlet and outlet pressure ranges? Generally speaking, you'll want a regulator designed to operate across a range beyond the pressures you are using. For instance, if the desired outlet pressure is 500 psi, you wouldn't want the control range operating 0 – 500 psig. You would want it rated at twice that. The middle is where you get the most accurate reading.
Will you be running a gas or a liquid through it? Gasses can be compressed, but liquids can't. That makes liquids a little easier to deal with.
What is the operating temperature?
What is the flow requirement?

Learn more about how to troubleshoot a regulator from Swagelok product managers and engineers:

Keep in mind that every regulator is susceptible to creep. That's an increase in outlet pressure that occurs when pressure escapes, even though the poppet is closed.

The root cause of the problem is in the seat itself. Regulator seats can be compromised by particulates in the process stream, which can cause minor imperfections in the sealing surface. The high flow and small orifice that is created in a pressure regulator combine to turn a very small particle into a fast projectile. This projectile can nick the sealing surface of the seat and cause leakage. Any other damage to the poppet or the seat can also cause creep. Using a regulator with a soft seat can reduce the opportunity for creep.

One good way to prevent creep is with upstream filtration. Make sure you are removing all particulates from the process stream before it reaches the regulator. Some regulators include an integral filter upstream of the seat to help protect the seat. This small filter can reduce the potential for creep and increase the life expectancy and accuracy of your regulator.

An increase in flow causes a decrease in outlet pressure in the case of pressure reducing regulators. This is called droop. It is primarily caused by the set spring. The more flow required, the more the set spring relaxes and loses load force, causing the outlet pressure to drop. This video highlights design strategies to reduce droop in a pressure-reducing regulator:

Droop can be prevented in several ways. By using a longer spring or by using a dome loaded regulator, the effect of droop can be minimized. You can also use a regulator with external feedback or with a pilot regulator, as they have flatter flow curves than a spring loaded regulator.
