ABSTRACT:
A pressure relief valve selectively permitting fluid flow through the valve if the pressure on one side of the valve exceeds the pressure on the other side of the valve by a set amount, the pressure relief valve including a first valve member having a valve seat surface, and a movable valve member adapted to releasably engage the first valve member. The movable valve member includes a body portion having a periphery, the periphery having a downwardly extending annular flange engaging the valve seat surface. The downwardly extending annular flange includes a generally spherical valve surface adapted to provide a seal with the valve seat surface by engaging a resilient sealing ring on the valve seat surface. A flexible diaphragm causes movement of the movable valve member away from the valve seat when the pressure on the other side of the valve exceeds the pressure on the one side of the valve by a selected amount. Further, the movable valve member moves away from the valve seat without the action of the diaphragm when the pressure on the one side of the valve exceeds the pressure on the other side of the valve by a selected amount.
