Balancing Valves

A balancing valve sets or holds the flow measurably so that each branch in heating and cooling circuits receives its design flow.
It is used to balance riser, floor and terminal unit circuits. The product range includes threaded static balancing valves (PN25, 1/2″–2″), flanged static valves (PN16, DN100–DN300) and cartridge dynamic balancing valves (PN16, DN65–DN300).
Main Applications
- Heating riser and floor circuits
- Chilled water distribution lines
- Fan coil and AHU circuits
- Heat exchanger secondary circuits
- District heating substations
- Flow balancing of existing systems
Technical Data
| Types | Static (threaded and flanged), dynamic (cartridge) (product range) |
|---|---|
| Threaded static | 1/2″, 3/4″, 1″, 1 1/4″, 1 1/2″, 2″; PN25 (product name) |
| Flanged static | DN100 – DN300; PN16 (product name) |
| Dynamic | DN65 – DN300; PN16, cartridge (product name) |
| Measurement | Test points (static types, depending on model) |
| Pre-setting | By handwheel (static types, depending on model) |
| Fluid | Heating and chilled water, glycol water (depending on model) |
| Temperature | Depending on model |
Material Options
| Part | Static balancing valve | Dynamic balancing valve | Combined (pressure-independent) valve |
|---|---|---|---|
| Operation | Manual pre-set, set by measurement | Cartridge holds the flow | Flow setting + control valve |
| Connection | Threaded or flanged | Flanged (cartridge) | Depending on model |
| Pressure class | PN25 threaded / PN16 flanged | PN16 | Depending on model |
| Typical use | Constant-flow circuits | Branches with varying pressure | Motorised terminal control |
Which material? A static valve creates a fixed resistance after setting, while a dynamic valve holds the flow even as differential pressure changes. Pressure classes are taken from product names; temperature and flow ranges are confirmed per model.
