Dynamic Balancing Valves
A dynamic balancing valve automatically holds the flow through it at a pre-set value, even when line pressure changes, thanks to the spring-loaded cartridge inside.
It is used in variable flow heating and cooling systems and for riser and main branch balancing. The product range includes cartridge dynamic balancing valves in PN16 from DN65 to DN300 in 8 sizes.
Main Applications
- Large heating risers
- Chilled water main branches
- AHU circuits
- District heating networks
- Variable flow pump systems
- Floor and block balancing

Material Options
| Part | Dynamic balancing valve | Static balancing valve |
|---|---|---|
| Flow behaviour | Constant despite pressure changes | Changes with pressure |
| Setting | Cartridge selection | Manual pre-set |
| Measurement need | Low | Commissioning measurement needed |
| Typical use | Variable flow system | Constant flow circuit |
Which material? As the flow of a dynamic valve is set by its cartridge, the design flow of each valve must be stated when ordering. The differential pressure range is confirmed from manufacturer data for the cartridge type.
