Abstract: The present disclosure relates to a rotary plug valve and, more particularly, to a rotary plug valve having a fluid conduit cartridge including components that are assembled in a manner allowing for the rotation of a valve handle without rotation of the entire valve or supply line. Illustratively, a retainer ring and a backer ring are coupled with a gripper ring positioned therebetween. Coupling of the retainer ring and the backer ring creates compression on locking tabs of the grip ring, holding the locking tabs in place between tangs of the backer ring and preventing rotation of the gripper ring.

Abstract: An illustrative dual outlet, single inlet, and single handle valve assembly is disclosed that allows a user to manipulate the handle to selectively allow or inhibit fluid flow from the single inlet to multiple fluid delivery devices. The valve assembly includes an indexing device to permit the user to choose between a variety of configurations that directs flow to a single fluid delivery device, multiple fluid delivery devices, or no fluid delivery devices.

Abstract: A plug valve assembly includes a valve carried in a valve body and including a spindle coupled to a plug. The spindle may have an appendage coupled to a sidewall of the plug, and circumferentially extending about a rotational axis less than 180 angular degrees, such that the spindle appendage is registrable with a valve body outlet to selectively reinforce the plug sidewall and thereby resist blowout of the plug sidewall into or through the valve body outlet. The spindle may be composed of nylon and the plug may be composed of liquid silicone rubber.

Abstract: 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.

Abstract: 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.

Abstract: A shield for preventing unauthorized manipulation of a fluid valve which can be retrofitted by the end user in place of the valve handle. The shield assembly includes a cylindrical shield member which is held on the valve assembly by a key adapter fastened to the valve stem in place of the valve handle. The key adapter includes a cavity for matingly receiving the valve stem such that rotation of the key adapter is transmitted to the valve stem for operation of the valve. The key adapter is positioned within the cylindrical shield preventing manipulation with a hand tool. The key adapter has a specially configured knob which is matingly engaged by a key for rotation of the key adapter and valve stem to selectively move the valve between its open and closed positions.
