Proportional Flow Control Valve

Proportional flow control valve is widely used in medical equipment or industrial applications, such as: gas-control welding equipment, ventilation equipment, laser machines, gas mixing, painting/spray equipment, semiconductor equipment, analytical equipment, anesthesia equipment, nebulizer, respiration measurement …etc.

Proportional Flow Control Valve


  • -Proportional solenoid valve:

The proportional solenoid converts the input current signal into a mechanical signal output, and then controls the flow. This type of proportional valve has fast response time, compact in size, and is suitable for installation on manifolds. Available flow ranges are 0-32L/min, 0-140L/min, 0-300L/min.

  • -Stepper-controlled proportional valve:

Kao Lu stepper-motor driven proportional valves control flow ranging from 0 to 20 LPM, 120 LPM, 300 LPM and up to 1000 LPM. Our stepper-motor driven proportional valves are ideal for controlling a variety of media such as water, gas, oil, etc. Kao Lu stepper-motor driven flow proportional valves also have the advantages of low hysteresis (<2%) and high resolution (20ml/min).
