Locally Built Swagelok Regulator Assemblies

Our engineers and technicians design and build pressure regulator assemblies for customers here in our Fremont, California shop. Swagelok Northern California offers regulator assemblies with the most-requested configurations for gas bottle or inline service, utilizing the KPR-Series pressure reducing regulator (KLF for 0-10 psig control range).

We are ready to discuss options, answer technical questions, and provide quotes. Please use the button to get in touch, or call 510-933-6200.

Standardized and engineered-to-order options

We offer over 30 types of regulators to suit a wide range of process, tank blanketing and instrument applications. If you are comfortable specifying your regulator assembly based on control range (psig), maximum inlet pressure (psig), and flow coefficient (Cv), great. We also offer ten popular configurations you can choose from, as well as additional options and configurations. Below are two example assemblies:

Example: Gas bottle regulator assembly

The KPR Series regulator shown here is a compact regulator with excellent accuracy, sensitivity, and setpoint pressure stability. KPR regulators feature a convoluted, non-perforated diaphragm; metal-to-metal diaphragm seal; low internal volume; two-piece cap design that provides linear load on the diaphragm seal; and high-flow, dual-gauze filter positively retained in inlet port.

Gas Bottle Regulator Assembly

Example: Inline regulator assembly

Swagelok-certified engineers are happy to handle all the necessary calculations, component selection, and design for you. We can provide a unique SKU for easy re-ordering. Or, build a Swagelok regulator assembly ordering number yourself by combining specific designators like assembly type, inlet connection, outlet connection, gauge ports, flow direction, etc. Either way, ordering copies is easy.

Benefits of delegating regulator assembly

Pressure control is challenging to get right in commercial fluid systems. Safety is on the line, as well as quality of output, production uptime, and labor invested over years in maintenance, repairs, and replacement. Regulators must be precisely integrated with other components to suit an application. With that in mind, let's compare having Swagelok build regulator assemblies to handling it in-house:

What to expect

Here are the main steps to preparing a custom pressure regulator assembly:

1. Design

Starting with a phone conversation, we gather information such as the assembly location, regulator assembly type, inlet connection, flow direction, and outlet connection. Depending on your application, we may ask additional questions about pressure ranges, working temperatures, and flow requirements.

2. Fabrication

Certified technicians handle fabrication, working in our Class 100 clean room if necessary. Swagelok assembly certification involves producing dozens of samples, each of which is inspected by Swagelok manufacturing engineers and put through destructive testing. Passing requires a 100% score.

3. Quality Control

Small batches are 100% quality controlled; large batches follow AQL Sampling rules. In addition to standard testing, we can do helium leak testing, hydrostatic testing, nitrogen pressure testing, and pressure decay testing. And every Swagelok product, assembly, and solution comes with Swagelok's warranty.

4. Delivery

We clean and either cap or bag the assembly to ensure contaminants are not introduced into your fluid system from the assembly. A test certificate is packaged with each assembly. Orders ship daily or can be picked up in Concord, Sunnyvale, or Fremont. Assemblies can be installed immediately. Give us a call if you need advice on installation.
