Rotary Valve Actuators
A rotary valve actuator is an electric drive that turns the stem of rotary-motion (rotary or ball type) HVAC valves by 90° to open, close or mix the flow.
It is used on heating circuit mixing valves, boiler and heat exchanger circuits and 2 and 3-way ball control valves. The product range includes 4 rotary actuators with different torque and control types.
Main Applications
- Heating circuit mixing valves
- Boiler return temperature boosting
- Heat exchanger circuit control
- 2 and 3-way ball control valves
- Underfloor heating mixing groups
- Chilled water circuit isolation
Technical Data

|---|---|
| Motion | 90° (depending on model) |
| Supply | AC 230 V or AC/DC 24 V (depending on model) |
| Control | On-off, 3-point or 0–10 V (depending on model) |
| Torque | Depending on model |
| Running time | Depending on model |
| Connection | With linkage kit to the valve stem (depending on model) |
| Compatibility | Rotary and ball HVAC valves |
Material Options
| Part | Rotary actuator · on-off | Rotary actuator · modulating |
|---|---|---|
| Control | Two-position or 3-point | 0–10 V |
| Typical valve | Isolation valve | Mixing valve |
| Connection | Linkage kit (depending on model) | Linkage kit (depending on model) |
| Use | Circuit isolation | Temperature mixing |
Which material? A compatible linkage kit must be used between rotary actuator and valve; the torque value is confirmed for the valve type. Control and supply vary by model.
