These safety relief valves serve the dual purpose of relieving (1) over pressure created by thermal expansion under normal ‘on and off’ firing conditions and (2) over pressure in the form of water

The only difference is the pressure relief valve acts as a safety feature to release pressure buildup. Conversely, the back pressure regulator is a part of the system to maintain a predetermined pressure. Norgas Controls provides gas regulators, gas valves, and gas meters for natural, propane, compressed, and sour gases across Canada.

3/29 · Relief valves are key components of pressure regulation mechanisms in hydraulic systems, and their performance directly determines the pressure stability and the safety of hydraulic systems [ 1, 2 ]. Many pieces of research work on the dynamic characteristics of relief valves have achieved valuable research results.

Choose BelGAS for your next backpressure regulator or back pressure regulator valve. A backpressure regulator or pressure relieving regulator can add an extra level of safety to your application. (304) 387-1200 | [email protected] (304) 387-1200 | info@

Pilot operated [two stage] pressure regulating relief valves have lower pressure override characteristics than direct operat-ed valves, although they are not as fast acting. They

A back pressure regulator is normally closed while a pressure reducing valve is normally open. Secondly, the back pressure regulator controls upstream pressure 

Industry leading pressure and safety relief valve designs with over 140 years of technical and application expertise providing custom engineered solutions for O&G, Refining, Chemical, Petrochemical, Process and Power applications. Our designs meet global and local codes and standards (API 526; ASME Section I, IV & VIII; EN ISO 4126; PED & more).

Limit the flow of water with a pressure-reducing valve. This device works by limiting how much pressure is inside the valve, causing friction and reducing the 

Zurn's water pressure regulator valve is ideal for residential & commercial applications. Check out our complete line of pressure vacuum breaker.

NOTE: See General Relief Valve Notes 1, 2, and 4 on page 5. Pressure Limiting and Regulating Relief Cartridges Sun pressure limiting and regulating relief cartridges are normally closed pressure control elements designed to maintain a constant pressure differential between port 1 (inlet) and port 2 (outlet) when oil flows through the valve.

Our safety relief valves are available in 0.187, 0.250, 0.281, and 0.375 inch insert diameters and 0.687 inch threaded configurations. They are constructed entirely of stainless steel and are available screened and unscreened. Built-in damping ensures quiet operation. Cracking pressures range from 20 to 5900 psid.
