Advantages of electronic pressure control distribution for Proportionair proportional valves


Accurate distribution of products in production lines and laboratory environments requires closed-loop technology. Regulating air pressure through a custom electronic pressure regulator provides precision monitoring and control instrumentation. Our dispensing applications include:

Adjust the pressure to control the head that dispenses the liquid product

Control of the punch pressure for dispensing food in the filling machine

Microfluidic dispensing

Repeatability

If you use a bucket of liquid on the production line, our products provide precisely controlled pressure on the top of the liquid, so when the valve is opened to dispense the liquid, the pressure is always the same.

If you manufacture a product on a continuous conveyor that requires glue beads (for example), our product allows you to increase the pressure and increase the flow when the production line accelerates or decelerates, ensuring that when dispensing glue, it is the same height and weight for each application.In a closed-loop system, this can go further. You may have a sensor to sense the size of the beads, and you will use it to close the loop. You can tell us how much pressure needs to be applied to ensure that the bead size is the same regardless of the line speed. This has extremely high accuracy.

High resolution

QPVresolution up to full-scale calibration+/- .005%. Sometimes the pressure is as low2 inches of water column——EveryPSI 28Inches of water.

One customer usedQPV to control the pressure of a large syringe that dispenses solder paste onto a circuit board. They need absolute precision——And the only way they can do that is by usingQPV. Without the high-resolution repeatable adjustment of this product, it is impossible to provide the required level of accuracy manually or mechanically. The product constantly changes the pressure by creating small differences in the command signal.
