Abstract:
A top entry check valve including a valve body with an access port and clapper assembly with a compressible hanger positioned in alignment with the access port. The compressible hanger comprises a plate member stamped from a sheet of metal 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 is connected to the hanger so that the clapper is movable between a closed position and an open position. A closure member has an abutment surface engaging the hanger so that the hanger body is compressed between the closure member and the valve body.
