Proportional Flow Control Valve, 2-Way
QSP10-20 = Poppet, 2-Way, Normally Closed =
A solenoid-operated, 2-way, normally closed, poppet-type, proportional, screw-in hydraulic cartridge valve for blocking or load-holding applications.
When de-energized, the QSP10-20 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 the② to ① flow path. Flow is proportional to current applied to the coil.
