The piston is connected for pivoting a valve member actuating rod enclosed within a flexible tubular projection of a Teflon valve body via a rocker arm engageable with a free end of the tubular projection. Connectors for inlet and outlet Teflon conduits to the Teflon valve body have hard plastic inserts mounted within inlet and outlet passageways of the valve body between conforming sealing surfaces of the valve body and conduits.
