DESCRIPTION
A solenoid-operated, two-way, normally closed, poppet-type, bi-directional blocking,
screw-in hydraulic cartridge valve, designed for low leakage in load-holding
applications.
OPERATION
When de-energized, the SV38-28 blocks fl ow in both directions. When energized, the
valve’s poppet opens on its seat, allowing fl ow from
to and to .
Consult factory if used serially with orifi ce disc.
Operation of Manual Override Option: To override, push and hold override button.
FEATURES
Continuous-duty rated coil.
Hardened seat for long life and low leakage.
Optional coil voltages and terminations.
Effi cient wet-armature construction.
Cartridges are voltage interchangeable.
Unitized, molded coil design.
Manual override option.
Optional waterproof E-Coils rated up to IP69K.
Industry common cavity.
