ABSTRACT:
A valve housing using a reciprocable valve disc plate for opening and closing off the water supply in the valve housing, as well as regulating the water flow between a fully closed and a fully open position. The disc plate is provided with guide follower members that cooperate with guide channels or tracks disposed respectively on opposite side walls of the valve housing for stabilizing the movement of the disc plate and for preventing chatter and undue wear and strain of the valve stem and its bushing that would ordinarily result from water turbulence in the valve housing.
