The performance of proportional valves falls in the wide spectrum between on/off solenoid valves and electrohydraulic servovalves. The valves are termed proportional because output flow is not exactly ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

For many projects that require control of air pressure, the usual option is to hook up a pump, maybe with a motor controller to turn it on and off, and work with that. If one’s requirements can’t be ...
