The first flow control valve controls fluid flow through the first outlet to the mixing chamber, and the second flow control valve controls fluid flow through the second outlet to the mixing chamber. The first and second outlets each have a size so that the mixing valve has a flow coefficient of approximately 2.5 in a mid-open position of both flow control valves, and the housing has a length dimension, a width dimension, and a thickness dimension, and the largest of these dimensions is no more than approximately 65 millimeters.

Abstract: A plumbing fixture having a body and a mixing valve provided within and separate from the body. The mixing valve has a housing that is separable from and disposed within the body, wherein the housing includes a mixing chamber for receiving cold water, hot water or a mixture thereof; a first flow control valve for controlling a flow of cold water to the mixing chamber; and a second flow control valve for controlling a flow of hot water to the mixing chamber. Each flow control valve has a first valve member, which is configured to engage with a valve seat of the housing in a closed position, and a second valve member, which is configured to engage with a separate valve seat of the housing in the closed position. A portion of the mixing chamber in the housing is located between the first and second flow control valves.

Abstract: A power operated valve for controlling fluid flow is provided with a fail-safe device responsive to failure of the power supply to the valve to shut-off fluid flow. A valve member is coupled to linear actuator for movement towards and away from a closed position for controlling fluid flow through the valve. The linear actuator is held in a control position by the fail-safe device for normal operation of the valve with the power supply on. The fail-safe device responds to failure of the power supply to release the linear actuator. When the linear actuator is released, energy stored n a spring while the linear actuator was held in the control position is released and biases the linear actuator away from the control position causing the valve member to move to the closed position to shut-off fluid flow.

Abstract: A flow control valve includes a valve inlet configured to receive a fluid, a valve outlet configured to output the fluid, and a valve member assembly for controlling the fluid flow through the flow control valve. The valve member assembly and the valve inlet are configured such that, when in use, fluid flowing through the flow control valve exerts substantially no net force on the valve member assembly.
