HY-SP10-20 (Poppet-type, 2-way, Normally Closed)
A solenoid-operated, 2-way, normally closed, poppet-type, proportional, screw-in hydraulic cartridge valve for blocking or load-loading applications.
Operation:
When de-energized, the HY-SP-10-20 acts as a check valve, allows flow from ① to ②, while blocking flow from ② to ①. when energized, the cartridge’s poppet lifts to open the ② to ① flow path. Flow is proportional to current applied to the coil. Flow varies with manual override.
