Abstract
A diaphragm valve is disclosed. The diaphragm valve includes a valve body including a housing defining a fluid flow passageway and a valve seat. A bonnet assembly including a housing is mounted to the valve body. A diaphragm, a backing cushion and a resilient member are positioned between the bonnet assembly and the valve body. The resilient member is sandwiched between the housing of the bonnet assembly and the backing cushion for urging the backing cushion toward the diaphragm, thereby urging the diaphragm against the valve body.
