Proportional valves

Proportional valves are specialised control valves that regulate the flow or pressure of a fluid (liquid or gas) in a system in a manner that is directly proportional to an input signal. Unlike traditional on/off solenoid valves, which are either fully open or fully closed, proportional valves offer precise control, allowing for variable flow rates or pressure adjustments based on the specific requirements of an application.

Application of proportional valves

1. Industrial automation
Used in automated manufacturing processes where precise control of flow or pressure is critical, such as in robotics, CNC machines, and process control systems.
2. Medical equipment
Employed in devices like ventilators, where the precise control of air or gas flow is necessary to ensure patient safety and comfort.
3. Aerospace
Utilised in fuel control systems and other applications where accurate flow control is vital for performance and safety.

Advantages of proportional valves

Precision: They allow for highly accurate control over flow and pressure, which is crucial in applications requiring exact performance.
Efficiency: Proportional control can lead to more efficient system operation, reducing energy consumption and wear on components.
Versatility: These valves can be used in a wide range of applications, from industrial machinery to medical devices, thanks to their ability to precisely control fluid dynamics.
