Northman pilot-operated check valve is designed to block the flow of oil in a hydraulic system to hold the position of a cylinder when the directional control valve is shifted to the neutral center position. Flow is restored by a pilot pressure signal releasing the check valve when the directional control valve is extending or retracting the cylinder. Valve mounts as a modular unit between a D03 size directional control valve and the subplate. Contains 2 separate pilot-operated check valves-one each on A cylinder port and B cylinder port. Requires longer than standard bolt kit to mount this flow control in valve stack. Max. Flow GPM 9.3, Max. PSI 3,000. Modular stack mount Cylinder position hold Model Number: MPC-02W-50-40. Size: 3. Color: Port. Age Group: Adult.
