R O D U C S E L E C I O N D GENERL D Models are direct solenoid operated four-way directional control valves. heir primary function, in a hydraulic circuit, is to determine the direction of fluid flow to a work cylinder, or control the direction of rotation of a fluid motor. ort connections are made y mounting the valve on a suplate or manifold. he valve has wet armature type solenoids. Electrical connections to the valve are made in the electrical wiring housing or y various plug-in devices. ground terminal is provided.
