Benefits
High Positioning Accuracy
The integrated SUT electronic positioner continuously monitors actuator position and automatically adapts to the connected valve stroke. This ensures accurate flow control and improved temperature stability while minimizing energy consumption.
Powerful 2500 N Output
With a thrust force of 2,500 N, the AVM234S can reliably operate medium and large Clorius control valves used in district heating, industrial processing, and marine systems.
Flexible Control Compatibility
The actuator automatically detects whether the controller provides an analog signal (0–10 V or 4–20 mA) or a switching signal (2-point or 3-point), reducing commissioning time and simplifying integration with PLC, DCS, or BMS systems.
Easy Commissioning and Maintenance
The patented actuator-to-valve coupling automatically connects the spindle during initialization. Manual override enables technicians to operate the valve during installation, testing, or maintenance without removing the actuator.
Typical Applications
The AVM234S is widely used in:
- District heating substations
- HVAC systems
- Industrial process control
- Steam and hot water systems
- Heat exchanger stations
- Thermal oil systems
- Marine cooling and heating
- Energy plants
- Utility process automation
- Building Management Systems (BMS).
