DESCRIPTION

A high pressure proportional solenoid-operated, two-way, piloted, poppet-type,

normally open, screw-in hydraulic cartridge valve for low-leakage blocking and load-

holding applications.

OPERATION

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 ener-

gized, 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.

FEATURES

• Industry-common cavity.

• Efficient wet-armature construction.

• Continuous-duty rated coils.

• Optional waterproof E-Coils rated up to IP69K.

• 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%.
