Why use a Proportional Valve?

A proportional valve provides a change in output pressure or flow in the same ratio as the change in the input; for example, if the input doubles then the output will also double.


This article outlines benefits and applications for these valves.


What are the key features?

Proportional Valves are suited to applications where output pressure will vary - either in steps or continuously. Stepped output pressure means the pressure is held at one value, before the pressure is increased to another value. Continuous output pressure is where pressure is continually increased at a set rate. Proportional valves are dependable, cost-effective (particularly air-pilot operated), give fast response and consistent control.

What are the benefits?

Proportional Valves can help reduce cycle times, by quickly achieving a stable pressure. They have a fast, precise response, which will improve efficiency. They also give repeatable control and pressure output, giving an expected response each time.

What are typical applications?

Proportional Valves are suited to analytical and test instrumentation, process applications such as tensioning, spraying and blow moulding. They are also found in medical and foundry applications. However, they can also be used in many other applications. Please contact us with any specific enquiries.
