A proportional solenoid-operated, four-way, three-position, spool-type, closed center, screw-in hydraulic cartridge valve.
When de-energized, the SP10-47C blocks flow to all ports. When coil S1 is energized, flow is allowed from 3 to 4, and from 2 to 1. When coil S2 is energized, flow is allowed from 3 to 2, and from 4 to 1.
Initial meter-in flow begins at a nominal 0.4 amp on a 12 VDC system. Full flow of 6 gpm occurs at 1.1 to 1.2 amp on a 12 VDC system. Each coil has its own metering characteristics, which are quite similar (see performance chart).
While port 1 may be fully pressurized, it is not intended for use as the valve’s inlet.
In circuits where work port flows are unequal due to cylinder ratios, the higher return flow should be directed to port 2.
• Continuous-duty rated solenoids.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Optional waterproof E-Coils rated up to IP69K.
• Optional manual override.
• Industry-common cavity.
• Designed for good linearity and hysteresis.
Operating Pressure: 248 bar (3600 psi)
Flow: 22.7 lpm (6 gpm) max. (see performance chart)
Internal Leakage: 164 cc/minute (10 cu. in./minute) max. per side at 248 bar (3600 psi)
Hysteresis: Less than 7%
Temperature: -40 to 120°C with standard Buna seals
Coil Duty Rating: Standard Coils and E-Coils: Continuous up to 115% of nominal voltage
Filtration: See page 9.010.1
Fluids: Mineral-based or synthetics with lubricating properties at viscosities of 7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1
Installation Recommendation: When possible, the valve should be mounted below the reservoir oil level. This will maintain oil in the armature preventing trapped air instability. If this is not feasible, mount the valve horizontally for best results. See page 9.020.1
Cavity: VC10-4; See page 9.110.1;
Cavity Tool: CT10-4XX; See page 8.600.1
Seal Kit: SK10-4X-MMM; See page 8.650.1
Coil Nut: Part No. 7004400;
Manual Override Coil Nut: Part No. 4528180
Coil Spacer: Std. D-Coil Spacer Part No. 7000280; E-Coil Spacer Part No. 4539700;If cartridge is ordered "Less Coil," D-Coil spacer will be provided unless an E is specified in the Coil Termination To Order section.
