HSV12-28 Valve

SYMBOL:HSV12-28 Valve symbol
DESCRIPTION
A solenoid-operated, two-way, normally closed, internally piloted, poppet-type,
bi-directional, screw-in hydraulic cartridge valve, designed to function as a
load-holding or blocking valve in applications requiring low internal leakage
bi-directionally.

OPERATION
When de-energized, the HSV12-28 blocks flow in both directions.
When energized, the valve’s poppet opens to allow bi-directional flow.

FEATURES
• 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.
• 1000-hour salt-spray rated solenoid tubes and coils.
• All HyPerformance products are tested to NFPA specification T2.6.1
  and are tested at a verification level of 90% and an assurance of 99%.
