A solenoid-operated, 2-way, normally open, piloted, poppet-type, screw-in hydraulic cartridge valve, designed to function as a load holding or blocking valve in high pressure applications requiring low internal leakage.
When de-energized, the HSV10-21 allows flow from 2 to 1 while flow from 1 to 2 is severely restricted in this mode.
When energized, the valve’s poppet closes on its seat, blocking flow from 2 to 1. In this mode the cartridge will allow 1 to 2 flow after overcoming the actuator and spring forces (see peformance graph).
Operation of Manual Override Option: The manual override feature is intended for emergency use, not for continuous duty operation. To shift the valve manually, push and hold down the manual override button/knob.
• Manual override options.• 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.• Waterproof E-Coils rated up to IP69K.• 1000-hour salt-spray rated solenoid tubes and coils.• Unitized, molded coil design.• 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%.
