ABSTRACT:
A plastic service valve includes a valve body of molded plastic having upper and lower chambers. The valve body is open at the top and bottom ends. The lower chamber includes inlet and outlet openings. A thrust seat is formed within the upper chamber between the open top end and the inlet and outlet openings in the lower chamber. A valve member is disposed in the valve body and positioned against the thrust seat. Structure is provided in the valve member and adjacent to the thrust seat for locking the valve member to the valve body. The valve member is molded of plastic material to form a unitary body including a plug portion and an actuator portion. The plug portion is rotatable in the valve body between an open position which is aligned with the inlet and outlet openings of the lower chamber of the valve body and a closed position. The actuator portion extends upwardly through the upper chamber portion and receives an operating nut.
