Pressure Relief Valves

Principle of Operation

Pressure Relief Valves are quick-opening, quick-closing valves used to protect equipment from gas pressure build up or pressure surges.  Standard applications involve steam, gases, or liquids where a tight seating valve is required to prevent overpressure. Typical applications are in process industries, pressure reducing stations, and turbine bleeder lines. These valves can also be equipped with a handwheel and screw spindle for either manually opening the disc or to facilitate changing the relief pressure by changing the compression of the spring.


Pressure Relief Valves are designed to meet specific requirements. Many variations are possible as these valves are custom engineered to suit the application.
