4 - WAY DIRECTIONAL CONTROL WITH PRESSURE COMPENSATED FLOW CONTROL • ADJUSTABLE PILOT OPERATED RELIEF VALVE is standard on every SDCF. FULL RANGE PRESSURE COMPENSATED by-pass type flow control valve built in. • SDCF REDUCES the number of fittings, plumbing and potential leaks in hydraulic circuits. • FINE POSITIVE METERING in either direction with the manual handle. • PRECISION GROUND IOSSO PLATED SPOOL that assures long life. • OPTIONAL O'RING PORTS to eliminate leakage. • 30 - Micron filtration recommended. • Cast Iron Body • IOSSO Plated Steel Spool • Consult Factory for Stainless Steel Spools

SDCF – GENERAL INFORMATION: The Brand, SDCF combines the features of a four-way directional control valve, a full range pressure compensated by-pass type flow control valve, and an adjustable pilot operated pressure relief valve all in one compact package. This valve reduces the number of fittings, plumbing and potential leakage points in hydraulic circuits. The manual handle allows the customer to meter the flow out of either port. Flow to the work port is directly proportional to the movement of the lever. Flow out of each work port is constant regardless of load changes, this allows the customer...

P T Open Center (O) - All of the ports are connected to tank when the spool is in neutral. Allows cylinder to move or motor to rotate when spool is in neutral. P T Tandem Center (T) - Powers cylinder or motor in both directions (metering capability is very limited). Pump unloads to tank when spool is in neutral. Cylinder or motor blocked when spool in neutral. A P T Fine Metering Spool (M) - The pressure drop in neutral is higher then the (OM) and (TM) spools. Requires external locking valves to hold cylinder, because ports A and B are open (orificed) in the neutral position. Extremely fine metering...
