Combined Balancing Valves
A combined balancing valve is a pressure-independent control valve that combines flow setting, differential pressure balancing and motorised control in a single body.
It is used instead of separate balancing and control valves on fan coil, AHU and terminal unit circuits. Size, flow range and actuator fit are confirmed per model; balancing valve actuators are in the product range.
Main Applications
- Fan coil circuits
- AHU heating-cooling coils
- Terminal unit control
- Variable flow systems
- Hotel and office buildings
- Reducing valve count in renovations
Technical Data
| Type | Combined (pressure-independent) balancing and control valve |
|---|---|
| Functions | Flow setting, differential pressure control, motorised control |
| Sizes | Depending on model, please ask |
| Pressure class | Depending on model |
| Actuator | Balancing valve actuators (product range) |
| Control | On-off or modulating (by actuator) |
| Fluid | Heating and chilled water (depending on model) |
| Temperature | Depending on model |
Material Options
| Part | Combined valve | Static balancing + control valve |
|---|---|---|
| Number of valves | 1 | 2 or more |
| Reaction to pressure change | Flow stays constant | Flow changes |
| Commissioning | Flow setting is enough | Measuring and setting needed |
| Installation | Compact | More space |
Which material? With a combined valve no separate balancing valve or differential pressure regulator is needed; the terminal unit design flow must be known for correct selection. Size and actuator fit are confirmed per model.
