Frequently Asked Questions

What is the purpose of a safety relief valve?

A safety relief valve protects pressure vessels, tanks, and piping systems from overpressure conditions by automatically opening to discharge fluid when the system pressure exceeds the set pressure. In fire protection, relief valves are installed on fire pump casings, compressor discharge lines, and air receivers to prevent catastrophic failure from excessive pressure accumulation.
