HydraForce Directional Control SP08-47C Spool-Type, 4-Way, 3-Position, Closed Centre


HydraForce SP08-47C solenoid-operated, 4-way, 3-position, spool-type, closed centre, screw-in hydraulic cartridge valve.

When de-energised, the SP08-47C valve blocks flow to all ports. When coil #1 is energised, flow is allowed from 3 to 4, and from 2 to 1. When coil #2 is energised, flow is allowed from 3 to 2, and from 4 to 1. In circuits where work port flows are unequal due to cylinder ratios, the higher return flow should be directed to port 2.

Initial meter-in flow begins at a nominal 0.4 amp on a 12 VDC system. Full flow of 11 lpm (3 gpm) occurs at 1.0 to 1.1 amp on a 12 VDC system.
