A balanced solenoid operated valve having a balanced solenoid plunger, and the valve can be made as a three-way valve or a four-way valve. In the four-way valve embodiment the solenoid plunger balancing means also functions as a sliding spool valve for controlling the flow of fluid through the valve between two valve ports. The four-way valve can be made with a valve body comprising an upper member and a lower member, and wherein the lower member can be adjusted relative to the upper member to vary the locations of the valve ports relative to each other.
