DESCRIPTION
A proportional solenoid-operated, 2-way, piloted, poppet-type, normally open, 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.
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%.
