HSP12-20 Valve

HSP12-20 Valve symbol


A high pressure proportional solenoid-operated, two-way, piloted, poppet-type,
normally closed, screw-in hydraulic cartridge valve for low-leakage blocking and
load-holding applications.

When de-energized, the HSP12-20 blocks flow from ports 2 to 1. In this mode, the
cartridge will allow flow from ports 1 to 2 after overcoming the spring forces
(see performance graph). When energized, the valve will allow flow proportional to the
applied current from ports 2 to 1 while severely restricting flow from ports 1 to 2.

Manual Override T Option: For normal operation, (de-energized) the manual override
button must be fully rotataed clockwise. To shift the valve manually, rotate the manual
override button counter-clockwise.

• Continuous-duty rated coil.
• Efficient wet-armature construction.
• Waterproof E-Coils rated up to IP69K.
• Linear metering and manual override options.
• 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%.

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.
