HSV12-28 Poppet, 2-Way, N.C., Bi-Directional Blocking
PERFORMANCE (Cartridge Only)
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-hold-
ing or blocking valve in applications requiring low internal leakage bi-directionally.
OPERATION
When energized, the HSV12-28 allows flow in both directions. When de-energized, the
valve blocks flow in both directions.
Operation of Manual Override Option: The manual override feature is intended
for emergency use, not continuous duty operation. To operate, the manual override
pin must be seated in the lower detent groove. To shift the valve manually, the opera-
tor pushes down on the knob and rotates 180 degrees in either direction. When the
manual override is actuated, increased flow can be achieved by pulling on the knob.
FEATURES
• Continuous-duty rated solenoid.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Manual override option.
• Waterproof E-Coils rated up to IP69K.
• Corrosion-resistant plating.
• Unitized, molded coil design.
• Cost effective cavity.
• All HyPerformance products are tested to the rigorous standards
of the NFPA specification T2.6.1.
• All HyPerformance valves are tested at a verification level of 90%
and an assurance of 99%.
