Safety Relief Valve

Definition - What does Safety Relief Valve mean?

Safety Relief Valve is a type of valve that is used to enhance the safety of a thermal-hydraulic plant. These valves release substances automatically from pressure vessels, boilers, or other systems while the temperature or pressure exceeds the preset limits. They are basically the automatic systems which relieve by the static pressure on both liquid and gas. They are also pressure relief systems that form the basic part of any processing facility, from the platforms of offshore production to the petrochemical complexes.

Petropedia explains Safety Relief Valve

Safety Relief Valves are manufactured in stainless steel or bronze or brass and provide a wide range of connections for operations up to 250 degrees Celsius. They are highly efficient, compact and incorporate seal technology for repeatable sealing performance of bubble-light. They are designed to carry out applications such as specialist gas plants, air or gas compressors, pressure vessels, chemical piping and equipment, medical gases and thermal relief, etc. They help in relieving pressure not obstructed by the back pressure and can handle higher built-up back pressures. They also have some disadvantages as they may emit toxic or inflammable substances to the atmosphere.
