Summit Hydraulics Hydraulic Monoblock Solenoid Directional Control Valve, 4 Spool, 21 GPM

Hydraulic Monoblock Solenoid Control Valve, 4 Spool, 21 GPM. Hydraulic Monoblock Valves are a style of Hydraulic Control valve. These valves start and stop fluid flow into hydraulic cylinders or hydraulic motors. The number of cylinders or motors that a control valve can operate depends on the number of spools on a valve. The flow rate listed shows the maximum allowed GPM (Gallons Per Minute) that can be put through a valve. A hydraulic control valve serves as a common example of the loader valve on a tractor. All spools are double acting with spring return to neutral position, A spool controls double acting cylinders A and B ports work as closed to Tank in neutral position. A and B ports are open to Tank in neutral position. Benefits: 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). Adjustable Relief Valve Range: 1500 to 3625 PSI. Preset Pressure Relief: 2610 PSI.
