ABSTRACT:
A large diameter in-the-field resettable rupture pin relief valve is formed by superposed valves normally closing a valve inlet port and released to open the port under excess pressure by collapsing the pin. Pressure operated cylinders connected with the superposed valves and pin supports reposition these components for replacing the collapsed pin without exhausting all fluid pressure in the valve.
