Description

HydraForce SP08-47D proportional solenoid-operated, direct-acting, 4-way, 3-position, spool-type, motor spool, screw-in hydraulic directional control cartridge valve.

When de-energised, the SP08-47D blocks flow to 3 while allowing flow from 2 to 1, and from 4 to 1. When coil S1 is energised flow is allowed from 3 to 4 and from 2 to 1. When coil S2 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.

Features:

• Continuous-duty rated solenoid
• Hardened precision spool and cage for long life
• Optional coil voltages and terminations
• Manual override option
• Optional waterproof E-Coils rated up to IP69K
• Efficient wet-armature construction
• Cartridges are voltage interchangeable
• Good linearity and hysteresis
• Industry-common cavity
