ABSTRACT:
An air operated double diaphragm includes an air valve, air chambers, a center section between the air chambers, pump chambers and diaphragms between the air and pump chambers harnessed together with a piston rod. The air valve includes a statically dissipative body having a bore therein with a statically insulative liner in the bore. The statically insulative liner is fully enclosed within the statically dissipative body. A valve element is slidably positioned in the liner. The liner includes annular tenons to mate with annular mortises in the statically dissipative body and an end cap is used to close the valve cylinder.
