A multi-passage coolant valve may include an outer housing including an outer body formed with a first outer inlet, a second outer inlet, a first outer outlet, and a second outer outlet, and an auxiliary body formed with a third outer outlet, and an inner housing rotatably provided in the outer housing. As the inner housing rotates by a predetermined angle, the first outer inlet and the first outer outlet are fluidly communicated with each other, the first outer inlet and the second outer outlet communicate with each other, and the second outer inlet and the third outer outlet communicate with each other.

Rotary valve systems with integrated sensors are described that facilitate stabilizing electrical connection from a valve actuator. A valve system includes a rotary valve comprising one or more ports configured to receive one or more fluids. The valve system further includes an actuator attached to the rotary valve, wherein the actuator comprises a power connection fed from electronics associated with the actuator. The valve system further includes an actuator cap attached to the actuator, the actuator cap configured to allow the power connection to pass through, wherein the actuator cap comprises one or more apertures, a valve collar with an integrated press-on connector configured to be attached to the actuator cap, wherein the valve collar comprises an electronic feedthrough passage for the power connection, a retainer portion comprising one or more retainer pins, wherein the one or more retainer pins are configured to mate with the one or more apertures on the actuator cap, the retainer portion configured to allow electrical connection between the power connector and a sensor connector when the one or more retainer pins fit within the one or more apertures on the actuator cap, and a sensor housing adjacent to the rotary valve and configured to support one or more sensors disposed with respect to one or more fluid lines coupled to the one or more ports of the rotary valve, the sensor connector configured to transmit signals from the one or more sensors to the actuator.

A multiple channel selector valve includes a stator and a rotor that is rotatable with respect to the stator. The rotor face includes first and second fluid flow paths for transferring fluids to selected sets of passages in the stator. The fluid flow paths in the rotor face are specifically configured to accommodate high fluid flow rate regimes while reducing flow restriction.

A valve having a flow trim assembly that can be quickly and efficiently removed and repaired or replaced. A body section having a central through bore that defines an inlet, an inner chamber or space, and two selectable outlets. Further the selectable outlets can direct flow in either a 90 degree “angle” orientation or at straight “in-line” orientation. An actuator stem extends into the inner chamber. A first (movable) trim member is attached to the rotator, and can be selectively rotated relative to a second (fixed) trim member. The first and second trim members cooperate to adjust flow opening through the valve. A valve bonnet that allows direct coupling of an actuator to the valve.

Disclosed is a friction ring including a body and a contact member. The body is configured to couple the friction ring to at least one of a faucet assembly or a faucet valve assembly. The contact member is disposed on the body. The contact member is configured to slidably engage with a valve stem of the faucet valve assembly. The contact member is further configured to press against the valve stem to increase a frictional force between the contact member and the valve stem over a full range of movement of the valve stem.

In a valve device, a rotor has a hole closing portion configured to increase or decrease a covered area of a first flow hole of a stator in response to rotation of the rotor. The hole closing portion has a hole closing portion edge which extends in a radial direction of a predetermined axis and is located at a circumferential end of the hole closing portion on one side in a circumferential direction. In a state where the first flow hole is closed by the hole closing portion, when the rotor is rotated toward another side, which is opposite to the one side in the circumferential direction, the hole closing portion begins to open the first flow hole. The first flow hole has a one-side hole edge which is located at a circumferential end of the first flow hole on the one side and extends in the radial direction.
