DASV10-22Poppet, 2-Way, Normally Closed

DESCRIPTION

A solenoid-operated, 2-way, normally closed, poppet-type,screw-in hydraulic cartridge valve, designed for low leakage blocking and load holding applications.

OPERATION

When de-energized，DASV10-22 acts as a check valve, allowing flow to pass from 1 to 2 , while blocking flow from 2 to 1 . With
the sensor option, the neutral sensor will signal ON or HIGH. When energized, the 2 to 1 flow path opens. In this mode, flow
is also allowed from 1 to 2 . With the sensor option, the neutral sensor will signal LOW or OFF.Operation of Manual Override Option: To override, push button in, twist counterclockwise 180° and release. In this position, the valve will remain open.To return to normal operation, push button in, twist clockwise 180° and release.Override will be detented in this position.
