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.


[ What is claimed is:] [1.] A valve and valve operator apparatus, comprising:a housing having a first end with a valve seat and a second end, and a housing wall therebetween;a valve assembly including a piston having a first end with a plunger for engaging the valve seat to block flow therethrough, a second end and a piston wall therebetween;a sealing ring outwardly extending from the piston wall;a cylinder surrounding said piston, having a fist end adjacent said valve seat and a second end remote from said valve seat;a mounting means for mounting the cy...
