HY-SP08-20 (Poppet-type, 2-way, Normally Closed)
Operation:When de-energized, the HY-SP-08-20 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.

Model |
HY-SP08-20 |
Installation position |
When possible, the valve should be mounted below the reservoir oil level. This will maintain oil in the armature preventing trapped air instability. If this is not feasible, mount the valve horizontally for best results. |
