A solenoid-operated, two-way, normally closed, internally piloted, poppet-type, bi-directional blocking, screw-in hydraulic cartridge valve, designed for low leakage in load-holding applications.
Product Operation
When de-energized, the SV12-28 blocks flow in both directions. When energized, the valve’s poppet opens on its seat, allowing flow from ➁ to ➀ or ➀ to ➁
Product Features
• Continuous-duty rated coil.
• Optional coil voltages and terminations.
• Effi cient wet-armature construction.
• Manual Override option.
• Cartridges are voltage interchangeable.
• Optional waterproof E-Coils rated up to IP69K.
• Hardened seat for long life and low leakage.
• Unitized, molded coil design.
• Cost-effective cavity.
