Safety valve

A safety valve is the final mechanical layer of overpressure protection. Selection must be based on the relieving scenario, set pressure, back pressure, fluid phase, required capacity and discharge system. Approximate sizing or line size alone is not acceptable.

Application and duty

Final protection against calculated overpressure scenarios
