Electro-Proportional Valve
  Proportional Flow Control Valve, 2-Way

QSP08-20  = Poppet, 2-Way, Normally Closed =



A solenoid-operated, 2-way, normally closed, proportional, poppet-type, screw-in hydraulic cartridge valve for blocking or load-holding applications.
When de-energized, the QSP08-20 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 ①1 flow path. Flow is proportional to current applied to the coil.
