HPV12-20 Valve
U.S. Patent 8,253,063


SYMBOL:
HPV12-20 Valve symbol

 

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

OPERATION
With inlet at port 1, the HPV12-20 will regulate flow out of port 2 regardless of system working
pressure with flow rate proportional to current applied to the solenoid.

FEATURES
• 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%.

RECOMMENDED ELECTRONIC CONTROLLERS
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.
