What are Proportional Valves? Essentially proportional valves are electronic flow controllers. Users can vary the input current to the solenoid, and the output flow of the valve will vary accordingly. The greater the input current, the greater the flow through the valve. Typical applications for proportional Humphrey valves are: dynamically dispensing controlled amounts of air Read the full article…
