| Solenoid On/Off Valve
Poppet-Type Solenoid Valve, Normally Open
QSV08-21 = Poppet, 2-Way, Normally Open =
A solenoid-operated, 2-way, normally open, piloted poppet-type, screw-in hydraulic cartridge valve designed for low leakage in load-holding applications.
When de-energized, the QSV08-21 allows flow from ② to ①, while flow from ① to ② is severely restricted.
For bi-directional capability, see model QSV08-23. When energized, the valve closes, blocking flow from ② to ①. In this mode, flow from ① to ② will be allowed after overcoming the solenoid force. This requires 3.4 to 10.3 bar (50 to 150 psi).
