ABSTRACT OF THE DISCLOSURE A molded, polyethylene valve body has a flow passage connecting an inlet with an outlet of the valve body. A valve seat, formed integral with the valve body, surrounds the passage and a plastic valve disc is rotatably positioned in the passage for movement into and out of sealing relation with the valve seat to effect closing and opening of the passage between the inlet and outlet. A valve stem is nonrotatably oonnected at one end to the valve disc and extends through the valve body and projects upwardly therefrom to an upper end portion. An actuator cap is nonrotat- ably connected to the valve stem upper end portion. An external valve neck portion surrounds the upper end portion of the valve stem and is positioned on the outer surface of the valve body. The neck portion is adapted to rotatably receive and support the actuator cap. A pair of clamp-like leg members of the neck portion extends circumferentially around the surface of the valve body to connect the neck portion to the valve body. Free end portions of the leg members are brought under tension to maintain the leg members in gripping engagement with the valve body so that the actuating forces from the actuator cap are transmitted from the neck portion and leg members uniformly around the surface of the valve body.
