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

OPERATION
When de-energized, the SV38-28 blocks blocks in both directions. When energized the poppet opens to allow flow in both directions. Consult factory if used serially with orifice 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.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
