HPV12-31 HyPerformance™ Proportional Flow, (HPV12-31)
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-compen-sated, 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.
Product Operation
With inlet flow at port 1, the HPV12-31 will regulate priority flow out of port 3 regard-less 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.
