Abstract
A valve device includes a base, and a faucet and a spray gun coupled to the base. A valve member is engaged in the base and has a chamber, and includes two valve seats disposed between the chamber and the faucet and between the chamber and the opening. A valve stem is slidably engaged in the valve member and has two plugs for engaging with the valve seats. A spring may bias one plug to engage with one valve seat and for preventing the water from flowing into the spray gun. The water is allowed to flow into the spray gun when the spray gun is actuated.
