Pneumatic Proportional Valve Selection Made Simple
Proportional valves — which change outputs in proportion to their input value — provide dependable, cost-effective, compact solutions for fast response and consistent control at relatively low flow rates. While proportional control technology is ideal when precise performance is required in variable pressure and flow applications, it may seem more complicated than other solenoid valves.
This paper will explain how to apply proportional valves correctly to yield real benefits in your design. It answers the three key questions in valve selection:
- Is the intended application suitable for a proportional valve?
- Does the application require an air-piloted or a direct-acting model?
- Would a proportional valve with special capabilities — such as software-based tuning — help me?
The paper's goal is to ensure selection of the correct valve for the designer's or user's needs.
