DASV08-20 Poppet, 2-Way, Normally Closed

DESCRIPTION

A solenoid-operated, 2-way, normally closed, piloted poppet-type,screw-in hydraulic cartridge valve, intended to act as a blocking or load-holding device for low flow circuits.

OPERATION

When de-energized, the DASV08-20 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. DASV08-22,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.
