| Solenoid On/Off Valve
Poppet-Type Solenoid Valve, Normally Closed
QSV12-22 = Poppet, 2-Way, Normally Closed =
A solenoid-operated, 2-way, normally closed, piloted poppet-type, screw-in hydraulic cartridge
valve, for blocking or load-holding in applications requiring low internal leakage.
When de-energized, the QSV12-20 acts as a check valve, allowing 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. In this mode, flow from ① to ② is severely restricted. If this path is required, see model QSV12-22.
