ABSTRACT:
The invention is a valve assembly designed for relieving pressure on a process structure, such as a reactor vessel or a pipeline. The valve structure consists of two separate pressure relief units, and each unit includes a pressure relief valve that is positioned between an inlet valve and an outlet valve. A single mechanical actuator means is used to open and close both pairs of valves, so that when one pair of inlet and outlet valves is fully closed, the other pair of inlet and outlet valves is fully open.
