A three-way pinch valve assembly is operated with a single solenoid with one pinch valve mounted on each end of the solenoid, one valve will normally be open and the other valve will normally be closed. The plunger of the solenoid is split so that each movable pinch bar of each pinch valve is separately adjustable. A back-up pinch bar for each movable pinch bar is likewise adjustable. A three-way valve is provided by connecting the tubing from the two pinch valves to a T-fitting having a single outlet.
