SV08-28 (SV08-28)
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.
