SP08-57D Spool, 5-Way, 3-Position… (SP08-57D)
A solenoid-operated, five-way, three-position, proportional, screw-in hydraulic cartridge valve with integral load-sense port.
Product Operation
When de-energized, the SP08-57D blocks flow at 5 while allowing flow from both 2 and 4 to 3. When coil #1 is energized, flow is allowed from 5 to 2, and from 4 to 3. When coil #2 is energized, flow is allowed from 5 to 4, and from 2 to 3. Load sense is connected to port 5 when the spool is in shifted positions.
Note: If low voltage is expected on the machine, 12 or 24 volt systems will require the use of 10 volt or 20 volt coils respectively. See “SP Valves and Coil Operating Parameters,” page 2.002.1.

• Continuous-duty rated solenoid.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations• Cartridges are voltage interchangeable.
