A common example of a hydraulic control valve is the loader valve on a tractor. Our monoblock valves have power beyond Capability (Power Beyond Adapter Sleeve is required SKU: P40-PB), as well as the ability to operate as a closed-center valve (Closed-Center Plug Required SKU: P40-CC). Operate hydraulic cylinders (Double-Acting or Single-Acting): Grapples (Tilt/Raise Cylinders), Box Blade (Height Adjustment). Install rear remotes on a tractor.
Raise/Lower Dump Truck Bed ("A" Spool). Operate Cylinders for Snow Plows ("A" Spools). A Spool (Controls Double Acting Cylinders). All spools are double acting with spring return to neutral position, A spool is designed to control double acting cylinders.
A and B ports are closed to Tank in neutral position. Precision ground and hard chrome-plated spools assure a long life. High-tensile strength cast iron monoblock construction. SAE O-Ring ports ensure solid seal and prevent blockages. Used for open center systems (Pump to Tank Flow).Capable of closed center or Power Beyond (conversion plug required). Adjustable Relief Valve Range: 1500 to 3625 PSI. DIN 43650 3 Prong Connectors. Max Operating Pressure: P = 3625 PSI, T = 725 PSI, A & B = 4350 PSI.
A & B Work Ports: #8 SAE O-Ring (3/4-16) Thread. Inlet Port: #10 SAE O-Ring (7/8-14) Thread. Outlet Port: #10 SAE O-Ring (7/8-14) Thread.
Nominal Voltage Tolerance +/- 10%.
