The pilot control responds to the differential pressure produced across an orifice plate installed downstream of the valve. Pressure relief valve, also known as the safety valve, can be automatically opened and closed according to the working pressure of the system, and is generally installed on the equipment or pipeline of the closed system to protect the safety of the system.
