HY-SP08-21 (Poppet-type, 2-way, Normally Open)
A solenoid-operated, 2-way, normally open, poppet-type, proportional, screw-in hydraulic cartridge valve for low-leakage load-loading applications, and for starting or stopping a load or a pump system.
Operation:
When de-energized, the HY-SP-08-21 allows flow from ② to ①. When the valve is partially energized, the valve begins to throttle the flow from ② to ①. When fully energized, the poppet closes on the seat, blocking flow from ② to ①. Flow from ① to ② will occur when hydraulic pressure exceeds the solenoid force.
