ABSTRACT:
The disclosed valve may be configured for use as a pressure relief valve, pressure regulator valve or pressure reducing valve. A pair of opposed valve members defines a radial flow path therebetween which extends from the outer radial peripheries of each valve member to an axial bore formed in one of the valve members. The other valve member comprises a substantially pressure balanced piston, the axial movements of which control flow through the valve. A pilot valve for relieving pressure above the piston has its inlet positioned within a cavity formed on the upper surface of the piston.
