DASV12-28 Poppet, 2-Way, N.C., Bi-Directional Blocking

DESCRIPTION

A solenoid-operated, two-way, normally closed, internally piloted, poppet-type,bi-directional blocking, screw-in hydraulic cartridge
valve, designed for low leakage in load-holding applications.

OPERATION

When de-energized，DASV12-28 blocks flow in both directions. When energized, the valve’s poppet opens on its seat, allowing
flow from 2 to 1 or 1 to 2 .

FEATURES

● Continuous-duty rated coil.
● Optional coil voltages and terminations.
● Efficient wet-armature construction.
● Manual OverrideOptions.
● Cartridges are voltage interchangeable.
● Optional waterproof E-Coils rated up to IP69K.
● Hardened seat for long life and low leakage.
● Unitized, molded coil design.
● Cost effective cavity.
