Two-year warranty
DASV12-22Poppet, 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 internalleakage.
OPERATION
When de-energized,DASV12-22 acts 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 is also allowed from 1 to 2,Operation of Manual Override Option: To override, push button in,twist counter clockwise 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.
FEATURES
● Continuous-duty rated solenoid.
● Hardened seat for long life and low leakage.
● Optional coil voltages and terminations.
● Efficient wet-armature construction.
● Cartridges are voltage interchangeable.
● Unitized, molded coil design.
● Manual OverrideOptions.
● Optional waterproof E-Coils rated up to IP69K.
● Cost effective cavity.
