Description
Precise linear control of control valves
The Belimo NRDVX24-3-T-SI linear water-side actuator is specially designed for positioning suitable control valves in water-side heating and cooling installations. The linear stroke converts the control signal into a precise valve position for stable water control. 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, running time and management are matched to the valve and to the required control behavior of the water circuit.
Key features & benefits
- 500 N – Reliable linear movement of the connected control valve
- 3-point – Connection to the desired control strategy
- IP40 – Suitable protection for use in technical installations
- Terminal blocks – Practical integration into the appropriate piping or mounting concept
- Linear valve control: controlled stroke movement for a precise valve position.
