HSP10-21 Valve

HSP10-21 Valve symbol


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

When de-energized, the HSP10-21 allows flow proportional to the applied current from
from ports 2 to 1 while severely restricting flow from ports 1 to 2. When energized, the
valve blocks flow from ports 1 to 2 after overcoming the spring and actuator forces
(see performance graph).
Note: If low voltage is expected on the machine, 12 or 24 volt systems will require the
use of 10 volt or 20 volt coils respectively.
See “SP Valves and Coil Operating Parameters,” page 2.002.1_pdf.

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.
