    摘要： A valve stem construction for a manipulable valve member used to control fluid flow through a valve. The valve stem extends externally of the valve housing for engagement by a valve handle used to manipulate the valve member between open and closed positions. The valve is formed with a plurality of circumferentially spaced concave splines extending longitudinally on the outer surface of the valve stem. The splines are spaced so as to maximize transmission of rotational torque while minimizing flexure and twisting of the valve stem. The spacing and configuration of the individual splines also ensure a strong mating fit with the valve handle.

    摘要： A stop valve includes a valve body, a multishot resilient control sleeve, O-ring and handle. The control sleeve is molded to the valve stem to create an integral but separately molded fluid control member. 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 control sleeve consists of a hard plastic cylinder and a flexible barrel member molded as one consistent piece by a multishot molding process. The O-ring also serves as a backup seal to prevent leakage to atmosphere. A valve handle is secured to the valve by either a screw or a snap protrusion.
