ABSTRACT:
A valve construction having a housing provided with an inlet and an outlet interconnected together by a valve seat of the housing carries a movable valve member for opening and closing the valve seat, the valve member having an elongated valve stem extending from one side thereof. The housing has axially spaced guides to provide the sole means for guiding axial movement of the valve stem, the valve stem having a guide collar thereon disposed closely adjacent the valve member and cooperating with one of the guides of the housing. Such guide collar is also utilized as a stop means for limiting axial movement of the valve member in one direction of movement thereof.
