Fittings are installed on the opposite side, and wiring of the solenoids is completed here at John Henry Foster prior to shipping. Once at the customer s facility, hydraulic lines are installed, and two plug-in electrical connections are made, and the unit is ready for service. This custom hydraulic package consists of a directional valve, flow control, and check valve for each of the four stations, as well as a four station manifold. Designed to operate a hydraulic motor circuit, each station has its own adjustable needle valve for low speed operation, as well as dual check valves to prevent oil back flow. The directional valves select slow speed by directing oil through the needle valve.
High speed is accomplished when the directional valve bypasses the restriction of the needle valve.
Four hydraulic motors are controlled from this single, compact assembly. John Henry Foster Co. Whether simple or complex, we would be happy to discuss any fluid power application you may have.
