QSV12-21

DESCRIPTION:
A solenoid-operated, 2-way, normally open, piloted poppet-type, screw-in hydraulic cartridge valve designed for low leakage in load-holding or blocking applications.
When energized, QSV12-21act as one -way valve, allowing flow from ①to ②, and blocks reverse flow. When de-energized, the spool lifts, valve allows flow from ② to ①, while flow from ① to ② is severely restricted. In this mode, flow from ① to ② will be allowed after overcoming the solenoid force. For bi-directional capability, see model QSV12-23.
