A pressure balanced solenoid operated valve includes a solenoid portion having a coil. A valve member portion is connected to the solenoid portion. The valve member portion has a body including first and second valve seats; and a first cavity positioned between the first valve seat and a valve outlet port. A valve member disposed in the body to be slid has a resilient valve element positioned between the first and second valve seats. The resilient valve element forms a valve closed position when in direct contact with the first valve seat. A bleed port is formed inside the body between the first valve seat and the valve outlet port, and opened into the first cavity to provide a flow path for pressurized fluid present at the second valve seat in the valve closed position to continuously flow out through the valve outlet port.
