SV12-28 Valve

SV12-28 Valve symbol

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

When de-energized, the SV12-28 blocks flow in both directions. When energized, the valves poppet opens to allow bi-directional flow.

• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Cost-effective cavity.
