SP16-20 Poppet, 2-Way, Normally Closed (SP16-20)
A proportional solenoid-operated, 2-way, poppet-type, normally closed, screw-in hydraulic cartridge valve for low-leakage blocking and load-holding applications.
Product Operation
When de-energized, the SP16-20 acts as a check valve, allowing flow from 1 to 2, and blocking flow from 2 to 1. When energized, the 2 to 1 flow path opens. Flow is proportional to current applied to the coil.
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.
