QSV16-21

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 de-energized, the QSV16-21 allows flow from ② to ①, while flow from ① to ② is severely restricted. 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).
