Abstract
The invention provides a method for using sacrificial buckling pin technology for a reliable actuated safety relief valve. The buckling pin fails at a predicted system pressure through transfer of force exerted by the system pressure on a sensing piston or diaphragm to the buckling pin. The buckling pin failure triggers the release of a latch mechanism that releases the actuator assembly to slide away from the valve seat to initiate relief flow. The use of the buckling pin as a trigger for release of a latch provides for valves with high flow rates without the use of large, unmanageable buckling pins.
