SP08-57D Valve

SYMBOL:SP08-57D Valve symbol
A solenoid-operated, 5-way, 3-position, proportional, spool-type, screw-in hydraulic
cartridge valve with integral load sense port.

When de-energized, the SP08-57D blocks flow at 5 while allowing flow from 2 to 3,
and from 4 to 3.
When coil S1 is energized flow is allowed from 5 to 2, and from 4 to 3.
When coil S2 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_pdf.

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.
