Description
Efficient shut-off and control at larger pipe diameters
The Belimo D6700NL butterfly valve is specially designed for controlling or shutting off water flows in larger HVAC pipelines. The compact rotary movement makes the butterfly valve suitable for high volumetric flows without a bulky valve body. The DN 700 sizing clearly shows for which pipe diameter this execution is intended.
Butterfly valves are widely used where larger pipe diameters and volumetric flows come together. The valve disc rotates in the pipeline, enabling a compact combination of shut-off function and control capability.
Key features & benefits
- 2-way execution – Targeted control or shut-off of one water circuit
- DN 700 – Clear sizing for connection to the corresponding pipe diameter
- Flange with Lug Holes (LUG types) PN 16 – Practical integration into the appropriate piping or mounting concept
- ps 1600 kPa – Designed for reliable operation within the specified system pressure
- kvs 11760 m³/h, kvmax 42800 m³/h – Matched to the specified design flow rate of the system
- Medium temperature -20…120°C – Suitable for the described heating and cooling applications
