Abstract: A valve system enables use of a standard single line faucet with a water treatment system, protects water treatment systems and other fluid flow devices from unnecessary fluid pressure, and regulates or prevents fluid flow to a dispenser or outlet in response to a particular event, such as a leak. The valve system includes a housing having ports for: (1) receiving a supply fluid, (2) supplying the fluid to a device, such as a water treatment system, (3) receiving the fluid from the device and (4) supplying fluid to a dispenser. The valve system also includes an automatic shutoff device within the housing that prevents water from flowing into the housing and the water treatment system when the dispensing outlet is closed and that allows water to flow through the housing and into the water treatment system when the outlet is open. The valve system may also include a second actuator connected to the automatic shutoff that is capable of moving the automatic shutoff to a partially or fully closed position.

A plurality of two-position valves are located in the structure at regular angular intervals at positions about the axis of the cylindrical structure. The valves are subject to mechanical actuation by axial displacement. A spindle co-axial with the axis has a passageway for the flow of air toward each axial end of the spindle. A pair of pawls are carried by the spindle, one on each side of the faces, for limited axial displacement and rotatable with respect to the cylindrical structure about the axis. The pawls are angularly displaced from each other so that when one pawl is aligned with a valve, the other pawl is angularly and axially misaligned. Resilient means (spring 6) urge the pawls axially away from the faces.
