DESCRIPTION
A solenoid-operated, 2-way, normally closed, poppet-type, internally piloted, screw-in hydraulic cartridge valve designed for bi-directional blocking in load-holding applications requiring low leakage.
OPERATION
When de-energized, the SV10-28 blocks flow in both directions.
When energized, the cartridge’s poppet lifts to allow flow in both directions.
FEATURES
• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Cartridges are voltage interchangeable.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
