DESCRIPTION
A proportional solenoid-operated, 2-way, normally open, poppet-type, proportional,
screw-inhydraulic cartridge valve for low-leakage blocking or load-holding applications.

OPERATION
When energized, the SP10-21 acts as a check valve, allowing flow from 1 to 2 while
blocking flow from 2 to 1. When de-energized, the poppet lifts to open the 2 to 1 flow
path. Flow rate varies with manual overide, screen and metering options.

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