SP10-47D Valve

SYMBOL:SP10-47D Valve symbol

A solenoid-operated, 4-way, 3-position, spool-type, motor spool,
screw-in hydraulic cartridge valve.

When de-energized, the SP10-47D blocks flow to 3 while allowing flow from 2 to 1,
and from 4 to 1.
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.
In circuits where work port flows are unequal due to cylinder ratios,
the higher return flow should be directed to port 2.
NOTE: While 1 may be fully pressurized, it is not intended for use as the valve’s inlet.

Initial meter-in flow begins at a nominal 0.4 amp on a 12 VDC system.
Full flow of 22 lpm (6 gpm) occurs at 1.0 to 1.1 amp on a 12 VDC system.
Each coil has its own metering characteristics, which are quite similar (see performance chart).

• 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.

Operating Pressure: 207 bar (3000 psi)
Flow: Up to 22 lpm (6 gpm) based on 50% duty-cycle and coil temperature of 20°C (140°F).
Consult factory if higher duty-cycle and coil temperatures are anticipated.
Internal Leakage: 246 cc/minute (15 cu. in./minute) max. per side at 207 bar (3000 psi)
Hysteresis: Less than 7%
Temperature: -40° to 100°C (-40° to 212°F) with Buna seals;
   -26° to 204°C (-15° to 400°F) with Fluorocarbon seals
Coil Duty Rating: 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: 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_4w
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. 7009280; 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

The EVDR Series controllers are recommended for use with most HydraForce proportional valves.
These newer electronic controllers are versatile, reliable, and easily configured and customized
for a wide range of applications. See the EVDR Product Selection Guide.
