ABSTRACT:
A diaphragm control valve including a casing having an opening in one side, a cylindrical pipe mounted in a coaxial relation to the casing and having a flange forming a valve seat at one end, a flexible diaphragm symmetrically mounted in the casing in a spaced relation to the valve seat, and a cover mounted on one end of the casing forming a pressure chamber on one side of the diaphragm. The chamber is pressurized to move the diaphragm toward the valve seat to control the flow of fluid across the valve seat. A number of ports or slots are provided in the valve seat to relieve pressure buildup on the valve seat.
