SP10-22 Valve

SYMBOL:

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

OPERATION
When de-energized, the SP10-22 acts as a check valve, allowing flow from 1 to 2, while blocking
flow from 2 to 1. When energized, the poppet lifts to open the 2 to 1 or 1 to 2 flow path.

FEATURES
• Bidirectional operation.
• Linear metering option.
• Continuous-duty rated coils.
• Protective screen option.
• Hardened steel work surfaces.
• Optional waterproof E-Coils rated up to IP69K.

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.
