Their primary function in ahydraulic circuit is to direct fluid flow to awork cylinder or to control the directionof rotation of a hydraulic connections are made by mountingthe valve on a manifold or subplatecontaining the are available with AC or DCwet- Armature solenoid (s).

3 Electricalconnections to the valve are made in anelectrical wiring housing or by variousplug-in devices.
