ELECTRO-PROPORTIONAL VALVES—FLOW CONTROL

DESCRIPTION

A solenoid-operated, electrically-variable, two-port, pressure-compensated, spool-type, normally closed when de-energized, 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 solenoid with optional coil voltages and terminations. Hardened spool and cage for long life. Efficient wet-armature construction. Cartridges are voltage interchangeable.

Unitized, molded, waterproof E-Coils rated up to IP69K. 1000-hour salt-spray rated solenoid tubes and coils.

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%.
