HSP16-21 Valve

U.S. Patent 8,253,063

SYMBOL:
HSP16-21 Valve symbol

 

DESCRIPTION
A proportional solenoid-operated, 2-way, piloted, normally open, poppet-type, screw-in hydraulic
cartridge valve for low-leakage blocking in high pressure load-holding applications requiring low
internal leakage.

OPERATION
When de-energized, the HSP16-21 allows flow proportional to the applied current from 2 to 1 while
severely restricting flow from 1 to 2. When energized, the valve blocks flow from ports 2 to 1. In this
mode, the cartridge will allow flow from 1 to 2 after overcoming the spring and actuator forces.
For normal operation (de-energized) the manual override button must be fully rotated counter-clockwise.

FEATURES
• Industry-common cavity.
• Efficient wet-armature construction.
• Continuous-duty rated coils.
• Optional waterproof E-Coils rated up to IP69K.
• 1000-hour salt-spray rated solenoid tubes.
• 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%.

RECOMMENDED ELECTRONIC CONTROLLERS
The EVDR Series controllers are recommended for use with most HydraForce proportional valves.
These newer electronic controllers are versatile, reliable, and easily configured and customized for a
wide range of applications. See the EVDR Product Selection Guide.
