ABSTRACT:
A dispensing valve suitable for food processing and other applications has a valving plunger formed as an integral part of a pneumatic piston. A valve seat receives the plunger end of the piston to perform a valving operation. The remainder of the piston includes chambering for pressurized air flow, moving the piston back and forth so as to operate the valve between closed and open positions.
