HSV12-21 Valve

HSV12-21 Valve symbol
A solenoid-operated, 2-way, piloted, normally open, poppet-type, screw-in hydraulic
cartridge valve, designed to function as a load holding in high-pressure applications
requiring low internal leakage.

When de-energized, the HSV12-2 1 allows flow from ports 2 to 1. while severly restricitng
flow from ports 1 to 2. When energized, the valve's poppet closes on its seat, blocking flow
from ports 1 to 2 after overcoming the actuator and spring forces (See performance graph).

Operation of Manual Override Option: The manual override feature is intended for
emergency use, not continuous duty operation. To shift the valve manually, push and
hold down the manual override button or knob.

• 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.
• Unitized, molded coil design.
• Corrosion-resistant plating.
• 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%.
