Pressure Regulators

A pressure regulator is a critical component in any gas or liquid control system. Forward reducing pressure regulators reduce high inlet pressures down to lower outlet pressures. Conversely, back pressure regulators are designed to control inlet pressures. From deep in the depths of the oceans to sky-high in aircraft, our back pressure and forward reducing pressure regulators cover pressure control from 0.1bar to 1,380bar (20,000psi) and port sizes from 1/8" to 3".

Product Range:

  • Analyzer & Instrumentation
    Typically incorporating Inconel® X750 diaphragm sensed elements to provide strength and flexibility, our Analyzer and Instrumentation range includes options from gas cylinder regulators to ATEX certified (2014/34/EU)  heated regulators.

  • High Pressure
    Piston-sensed high pressure regulators, typically with ceramic seating. These include our hydraulic range with precision machined and fully supported sensor elements to cover pressure ranges up to 1,034 bar (15,000 psi). Port sizes from 1/8” to 3/8”.

  • Medium Flow
    Primarily for gas service with diaphragm-sensed elements to control up to 10 bar (145 psi), and piston-sensed elements covering up to 414 bar (6,000 psi). Ports 1/2” to 1”.

  • High-Flow
    ASTM F436 Hardened Steel Flat Washers, Stainless Steel and Belleville Washers.

  • Back Pressure
    Covering port sizes from 1/8” to 2” and controlling pressures from 0.1 bar (2 psi) to 690 bar (10,000 psi) on gas or liquid applications. Accurate and repeatable shut-off.

  • Diving
    Our brass regulators are cleaned and degreased within the guidelines of ASTM G93 for equipment used in oxygen-enriched environments, and intended for use on critical life support or hyperbaric diving applications.

  • Hydrogen
    Back pressure and forward reducing regulators for applications such as drones, forklifts, refueling stations, buses/trucks and electrolysis. This range includes products with EC79 and TPED approvals.

  • Subsea
    Designed to operate at depths of up to 3,000m (10,000ft), our subsea pressure regulators can either use external seawater pressure as a reference pressure, or, they can be sealed to operate at topside ambient pressure conditions.

A.R. Thomson Group Inc. is very proud to announce our partnership with Pressure Tech Ltd, a global manufacturer of high-quality ISO-9000 certified pressure regulators. We will now supply and service the Canadian market with a wide range of liquid and gas regulators for standard applications as well as the most demanding service involving high flow and Ultra-high pressures. 

Mark Matson: “Our customers tell us they need a high-quality regulator line with reliable delivery and a breadth of product to handle their full range of flow and pressure requirements. Our partnership with Pressure Tech Ltd allows A.R. Thomson Group Inc. to meet these demands and further support our customers critical operations."
