SV38-28 (SV38-28)
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.
Product Operation
When de-energized, the SV38-28 blocks flow in both directions. When energized, the
valve’s poppet opens on its seat, allowing flow from ➁ to ➀ and ➀ to ➁. Consult factory if used serially with orifice disc.
Operation of Manual Override Option: To override, push and hold override button.
Product 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.
