Use of Proportional Valves in the HVAC Sector

In HVAC systems, proportional valves are control elements that can adjust fluid flow gradually. Unlike traditional on/off valves, proportional valves provide precise control between 0–100%. This feature increases energy efficiency and enhances comfort levels.

Applications

Precise room temperature control in fan-coil units

Regulation of cooling/heating flow in AHU (Air Handling Unit) coils

Load balancing in chiller and boiler circuits

Flow optimization in central heating and cooling systems

Advantages

Energy savings: Prevents unnecessary flow and temperature fluctuations

Comfort: Maintains stable ambient temperature, reducing variations

Equipment lifespan: Gradual control reduces mechanical stress compared to sudden on/off actions

Process stability: Works with PID control to maintain product quality in industrial lines

Proportional valve usage has now become a standard in modern HVAC projects. With proper valve selection and control integration, businesses can reduce energy costs while improving user comfort.
