Device and method for operating at least two valves

A valve device, comprising

• a main body constructed to receive a first valve and a second valve, said first valve including a first fluid input port and a first fluid output port, said second valve including a second fluid input port and a second fluid output port;
• a pilot mechanism for simultaneously controlling flow of a first fluid between said first input and output ports and flow of a second fluid between said second input and output ports;
• and
• a check valve co-operatively constructed with said pilot mechanism and arranged to prevent mixing of said first and second fluids.

A method for controlling flow in at least two fluid lines, comprising the acts of:

• providing a main body arranged to receive a first valve and a second valve, said main body including a pilot mechanism and a check valve;
• triggering said pilot mechanism at said main body using a single actuator to change a state of both said valves;
• changing the state of both said valves;
• and
• preventing fluid flow between said first and second valves using said check valve.

A valve device for simultaneously controlling fluid flow in separate fluid lines, comprising:

• a first valve including a first fluid input port and a first fluid output port, and a second valve including a second fluid input port and a second fluid output port;
• an automatic actuator arranged to automatically control a pilot mechanism for simultaneously controlling flow of first fluid between said first input and output ports and flow of second fluid between said second input and output ports;
• and
• a manual actuator arranged to manually control said pilot mechanism.

A method for controlling water flow in an automatic faucet system including a water outlet above a sink, comprising the acts of:

• providing a main body arranged to receive a first valve and a second valve, said main body including a pilot mechanism and a check valve;
• providing a manual actuator connected to a manual actuator control arranged in a control passage, said manual actuator control including a handle located near said water outlet and an elongated body located in a control passage;
• and
• triggering said pilot mechanism at said main body using said manual actuator control and thereby changing a state of both said valves.
