Abstract
A solenoid-actuated four-way fluid control valve assembly has a body assembly mounting a pair of solenoids and defining two valve chambers each containing an axially elongated generally L-shaped plunger assembly and a pair of valve seats. Each plunger is spring biased to closing engagement with one of the valve seats and is shiftable axially to another position to open the one valve seat and close the other in response to energization of an associated one of the solenoids. A transfer plate mounted on the valve body determines flow paths through the valve assembly and carries needle valves for selectively regulating flow in each of the latter paths. The two plunger assemblies, the biasing springs therefor, and a cartridge which provides a closure for the two valve chambers comprise a cartridge assembly which may be removed from the valve body as a unit to facilitate repair or replacement of operational parts of the valve assembly.
