DESCRIPTION
A solenoid-operated, 2-way, normally closed, poppet-type, proportional, screw-in
hydraulic cartridge valve for blocking or load-holding applications.

OPERATION
When de-energized, the SP10-20 acts as a check valve, allowing flow from 1 to 2,
while blocking flow from 2 to 1. When energized, the cartridge’s poppet lifts to open
the 2 to 1 flow path. Flow is proportional to current applied to the coil. Flow varies with
manual override.
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.

FEATURES
• Continuous-duty rated coil.
• Efficient wet-armature construction.
• Manual override options.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
• Metering option.

RECOMMENDED ELECTRONIC CONTROLLERS
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. For other Electronic Controllers, see page 2.001.1_pdf
