HPV12-21 Valve

U.S. Patent 8,253,063

HPV12-21 Valve symbol


A solenoid-operated, electrically-variable, two-port, normally open when de-energized,
pressure-compensated, spool-type, proportional flow control valve for high pressure
applications up to 350 bar (5075 psi).

With inlet at port 1, the HPV12-21 will regulate flow out of port 2 regardless of system
working pressure. Increasing current applied to the solenoid will decrease output flow.

• Continuous-duty rated coil.
• Hardened spool and cage for long life.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• 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%.

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.
