Abstract
A three-piece angle stop valve comprises a valve body, resilient control sleeve and handle, with no separate fastening or sealing elements required. Inlet line pressure resiliently biases the side walls of the control sleeve and a circumferential sealing flap formed thereon into sealing engagement with the valve bore to prevent leakage. The handle is secured to the valve body by resilient formations which snap into a circumferential groove on the valve body. The handle rotates the control sleeve by means of telescoping splines. Several circumferential and axial reinforcing ribs are formed in the interior of the control sleeve. A collar having a tapered rim in the valve body piercingly engages a corresponding tapered section on the resilient control sleeve to additionally secure the control sleeve against axial downstream movement in the valve body.
