HydraForce, Inc. Spool-Type, 3-Port, Normally Closed, Control Valve Flow Control HyPerformance® HPV16-31

A high pressure, solenoid-operated, pressure-compensated , spool-type, normally open, priority type 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 HPV16-31 will regulate priority flow out of port 3 regardless of system working pressure, with flow rate inversely proportional to the current applied to the solenoid. Excess flow will bypass out of port 2. The bypass flow can be used for auxiliary function control. Note: Avoid dead-heading of priority line by external valving to prevent blocking of bypass line. In resstrictive 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.
