Pressure relief valves (safety relief valves) are designed to open at a preset pressure and discharge fluid until the pressure drops to acceptable levels. Pressure relief valves are used in a wide range of specifications where pressure levels are critical for smooth operations such as oil and gas, petrochemical, and power generation using steam, air, gas, or liquid. They are also used in multi-phase applications in refining and chemical processing systems.
ATO.com online store offers spring-loaded pressure relief valves of a wide range from 1/2" to 2", the valve opens to ease the building pressure by allowing it to escape, and the valve then closes when it returns to a stable level. It prevents potential injury, limits the failure of equipment, and controls the pressure in a system with a point of release.
