Balance and Control Valves
Precision Flow Control for Efficient Heating, Cooling & Potable Systems
The complete range of NexusValve includes all types of static and dynamic balancing valves, differential pressure regulators and pre-adjustable lockable ball valves from DN15 to> DN300. The innovative NexusValve technology makes efficient installation and easy hydraulic balancing possible. Optimised valve construction and coordinated partner valves ensure perfect interaction and simplification of maintenance and service in the installation system. Manual pre-setting is possible due to the effective measurement and flow rate adjustment of the compact NexusValve measuring computer.

NexusValve TW for domestic water
The NexusValve BC3 instrument is designed for hydraulic balancing of heating and cooling systems. It allows measuring static pressure, differential pressures and flow in the said systems. Using the differential pressure measured by the measuring component (balancing valve or measuring orifice). The application corrects the calculated flow also for anti-freeze mixes in cooling systems. The flow can be measured in all branches of the whole hydraulic system, and the whole system can be balanced.
The NexusValve BC3 App is available for Android and iOS.
- Ergonomic, user-friendly measuring device.
- Fully differential pressure sensor with 24-bit pressure processing.
- Digital compensation of temperature effects and the pressure sensor nonlinearity.
- User application for mobile devices running the Android operating system (7.0 +) / iOS.
- Wireless data transfer.
- Correction of flow calculation based on antifreeze liquid characteristics.
- Easy balancing valve selection from a photographic menu.
- Project records with a capacity of up to 2000 recordings.
