DASV12-20Poppet, 2-Way, Normally Closed

DESCRIPTION

A solenoid-operated, 2-way, normally closed, poppet-type,screw-in hydraulic cartridge valve, designed to function as a load holding or blocking valve in applications requiring low internal leakage.

OPERATION

When de-energized,DASV12-20acts as a check valve, allowing flow to pass from 1 to 2 , while blocking flow in the reverse direction. When energized, the poppet lifts to open the 2 to 1 flow path. In this mode,flow from 1 to 2 is severely restricted. Operation of Manual Override Option: To override, push button in, twist counterclockwise180 ° and release. In this position, the will remain open.To return to normal operation, push button in, twist clockwise 180° and release. Override will be detented in this position.

FEATURES

● Continuous-duty rated solenoid.

● Efficient wet-armature construction.
● Cartridges are voltage interchangeable.
● Manual OverrideOption
● Optional waterproof E-Coils rated up to IP69K.
● Unitized, molded coil design.
● Cost effective cavity.
