Description
Precise linear control of Control valves
The Belimo NRD24-SR-SI linear hydronic actuator is specially designed for positioning suitable Control valves in hydronic heating and cooling systems. The linear stroke converts the control signal into a precise valve position for stable water regulation. The actuating force of 500 N supports reliable movement of the connected Control valve.
The actuator operates the stem of a compatible Control valve. Actuating force, stroke, travel time and Management are matched to the valve and to the required control behavior of the water circuit.
Important features & benefits
- 500 N – Reliable linear movement of the connected Control valve
- 0…10 V – Targeted measuring execution for connection to the control system
- IP40 – Suitable protection for use in technical installations
- Cable – Practical integration in the appropriate piping or mounting concept
- Linear valve operation: controlled stroke movement for precise valve positioning.
