DASV10-28 Poppet, 2-Way, N.C., Bi-Directional Blocking

DESCRIPTION

A solenoid-operated, 2-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，DASV10-28 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.
● Cartridges are voltage interchangeable.
● Optional waterproof E-Coils rated up to IP69K.
● Hardened seat for long life and low leakage.
● Manual OverrideOptions.
● Industry common cavity.
