HPV12-31 Valve
U.S. Patent 8,253,063

SYMBOL:
HPV12-31 Valve symbol

 

DESCRIPTION
A high pressure, solenoid-operated, electrically-variable, three-port, pressure-compensated,
spool-type, normally open when de-energized, proportional flow control valve. It can be used as a priority-type flow regulator with pressure-compensated, regulated and bypass flow. It can also be
used as a restrictive-type 2-way, pressure-compensated flow regulator when the bypass line
(port 2) is blocked.

OPERATION
With inlet flow at port 1, the HPV12-31 will regulate priority flow out of port 3 regardless of system
working pressure, with flow rate inversely proportional to current applied to the solenoid. Excess flow will bypass out of port 2 and can be used for auxiliary function control.
Note: Avoid dead-heading of priority line by external valving to prevent blocking of bypass line. In
restrictive mode applications, bypass port 2 has to be blocked. Flow rate out of port 3 remains
inversely proportional to current applied to the solenoid regardless of load (pressure) applied to port 3.

FEATURES
• Excellent linearity and hysteresis.
• Hardened spool and cage for long life.
• Compensated flow control.
• Efficient wet-armature construction.
• Patented high-strength solenoid tube.
• 2 or 3-ported operation.
• Uses more compact 10-size coil.
• Coil waterproofing standard.
• 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%.
