Pressure relief safety valve at SystemTechnology is designed as a pop-up type valve. On exceeding set pressure the valve opens to discharge the excess built up the pressure.
After relieving excess pressure, the valve automatically returns to the original position. The bronze internals ( Seat & Plug ) ensure that there is no leakage while in operation.
