Product Description

A solenoid-operated, 2-way, normally closed, direct-acting, poppet-type, bi-directional blocking, screw-in hydraulic cartridge valve, designed for low leakage in load-holding applications.

Product Operation

When de-energized, the SV08-28 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.Operation of Manual Override Option: To override, push and hold override button.

Product 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 override option.
Industry common cavity.
