Need High-flow Process Regulators? Ask for RHPS

by Katie Reid, on Wed, May 04, 2016 @ 14:05 PM

We sent our associates right to the source for training and a tour of the factory

  Pressure Regulators RHPS Series, pictured above, are available in sizes up to 4 inches with a working pressure up to 10,500 psi. To learn more about this regulator product line download the RHPS Series catalogue here.

When Swagelok wanted to add a line of high-flow process regulators, nothing could top the ones made by a company called RHPS. So Swagelok bought the company.

Pressure Regulators RHPS Series have been engineered for applications in the chemical/petrochemical, oil and gas, power, biopharmaceutical, semiconductor, and alternative fuels industries. Made of 316L stainless steel, the RHPS Series is more structurally sound than the cast designs and carbon steel used by some competitors. The cartridge design allows you to change the seat without taking the whole regulator out of the line. The series includes pressure-reducing regulators, back-pressure regulators and specialty regulators for applications such as tank blanketing.

RHPS Series regulators come in several different models: spring-loaded, dome-loaded and pilot models, in standard sizes up to 4 inches, and with customized flange sizes over 4 inches. The working pressure of the RHPS Series line up to 10,500 psi, but it also can handle challenging applications that require high flow or volume and only inches of water column pressure control.

RHPS training trip

To ensure we had the RHPS Series expertise in Edmonton, we sent two of our associates to the Isle of Man a few months ago to tour the factory where the regulators are made. Custom Solutions Manager/Swagelok field service technician Stacey Phillips and Drayton Valley account manager David Flett spent five days getting a thorough education.

"We went through the whole product line of the RHPS, learning all the different models that they have, and how to size regulators," Flett says.

The factory, which is also where Swagelok has its aerospace division, has 235 associates. That makes it a major employer on an island with a population of only about 85,000. With a capable work force, and with airplanes and ships always coming and going, the island makes a good base from which the RHPS factory can serve the world.

"The thing that stuck with me the most is that they're very quick to respond to special requests, especially for the RHPS line," Flett says. "They want to really support engineered-to-order and configured-to-order requests."

There also was a little bit of free time to check out the sights on the island, which sits in the Irish Sea between England and Ireland. Motorcycle fans know the island as the site of the International Isle of Man Tourist Trophy Race, known more familiarly as the TT Race. Our associates got to tour part of the 37-mile course and talk to a past winner.

Now with CRNs

Most of the RHPS Series line already has CRN numbers, and we're working on the remainder. It's a large line, so if you want a particular RHPS regulator model that doesn't yet have its CRN number, don't worry. We will do our best to find one that will take care of your needs.

We can also troubleshoot regulators, eliminating or minimizing poor performance characteristics that can cause droop, choked flow, lock-up, hysteresis the Joule-Thomson effect.

Does it sound like we know a lot about RHPS regulators? We do. We'd like to share that knowledge with you. Download the Pressure Regulators RHPS Series catalogue, and then talk with us about the model that will work best for you.
