SP10-21 Valve SYMBOL:
SP10-21 Valve symbol
A proportional solenoid-operated, 2-way, normally open, poppet-type, proportional,
screw-inhydraulic cartridge valve for low-leakage blocking or load-holding applications.

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.

• 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.

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.
