Abstract
A faucet system includes a cold water control valve and a hot water control valve. These control valves are in communication with each other through a cold water supply conduit and a mixed water conduit. The hot water control valve includes a needle valve and a valve seat. The needle valve is adjustable with respect to the valve seat to adjust the maximum temperature of hot water being supplied by the hot water control valve to the mixed water conduit. In one embodiment, the hot water control valve of the faucet system further includes a pressure balancer disposed between the hot and cold water supply and the hot and cold control valves.
