A proportional solenoid-operated, two-way, poppet-type, normally closed, screw-in hydraulic cartridge valve for low-leakage blocking and load-holding applications.
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 2 to 1 flow path opens. 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.
