Claim:
A valve, comprising: a valve body having an inlet port, an outlet port, a flow passage extending between the inlet port and the outlet port, and an access port; a valve seat defined about the inlet port of the valve body; a compressible hanger engaging a portion of the valve body and positioned in alignment with the access port of the valve body, the compressible hanger comprising a plate member stamped from a sheet of metal, the plate member having a front end, a rear end, a first side, a second side, an upper end, and a lower end, the plate member having a body portion and a pair of wings extending laterally from the body portion, the body portion contoured to define a hinge pin receiving groove traversing the body portion, each of the wings having a proximal portion and a distal portion, the proximal portion of each wing having at least one dimple formed in one of the upper side and the lower side and a corresponding protuberance formed on an opposing side so as to define a compressible area; a clapper having a valve disc and a hinge pin, the hinge pin being disposed in the hinge pin receiving groove such that the valve disc is movable between a closed position wherein the valve disc engages the valve seat to occlude the passage of fluid through the fluid flow passage and an open position wherein the valve disc is moved away from the valve seat to permit passage of fluid through the fluid flow passage; and a closure member connected to the valve body to close the access port of the valve body, the closure member having an abutment surface engaging the compressible areas of the hanger so that the hanger is compressed between the closure member and the valve body.
