Pressure relief valves are safety devices that automatically discharge fluid when system pressure exceeds preset limits. They protect piping systems, tanks, and equipment from pressure build-up that could cause mechanical failure or explosions. These valves are critical in industries such as oil & gas, chemical manufacturing, and HVAC.

They are engineered for accuracy and fast response, and come in spring-loaded, pilot-operated, and balanced bellows designs. Materials range from stainless steel to bronze, depending on the application medium and environment. Regular calibration and testing ensure safe operation over time.
