HVAC hydronics – the goldmine in building renovation projects.
The smart control of heating, cooling, and ventilation loads has a big impact on the energy efficiency of buildings. A key aspect here is the heating and chilled water circuit, i.e. the hydronics of a building.
Generation
- No energy loss at zero load reduces operating costs.
- Planning reliability as a first step towards better energy efficiency.
Distribution
- Pressure fluctuations in distribution lead to lower power output.
- Making energy flow visible.
Zone
- Demand-driven zone control.

Customer-specific products
These days, challenges in planning and on the construction site are difficult to solve using standard products, which is why customer-specific solutions are becoming increasingly important. We build the actuator you need – with the cable length, connector plug and parametrisation you specify. On request, we mount the actuator to a valve and create a pre-mounted assembly from pipe parts, sensors, connections and much more.
- Different cable types and lengths with or without a connector plug.
- Product labelling with your customer information (e.g. where the actuator is to be installed in the building).
- Completely prefabricated and tested assembly (e.g. seal integrity) with components of your choice.
- On request with flexible pipelines, with special coatings or insulation.
- We take care of the parametrisation for you (e.g. adjustable running time, switching differential and bus parameters). For HVAC performance devices (e.g. Belimo Energy Valve™), we prepare the complete commissioning for you according to your specifications.
We offer a "complete carefree package" for your application.
- Customer advantages
- Software / Plug-ins
General contractors / investors
Your focus is on the profitability of buildings. This not only includes investment costs, but also costs during ongoing operation / servicing. Sustainability and cost transparency are important to you. Belimo characterised control valves offer:
- Tested quality for over 40 years
- Reduced current consumption compared to conventional valves, which contributes to LEED certification
- Tight-closing characterised control valves prevent valve leakages and thereby energy losses
- 5-year guarantee on all Belimo products
Consulting engineers
Planning HVAC systems is your core competence. You are constantly on the lookout for new, innovative ways to save energy and improve room climate. You work with the most modern methods and use data from suppliers / manufacturers for your planning. Belimo characterised control valves offer:
- 0% leakage rate for increased plant efficiency
- Spring-return actuators and fail-safe actuators open or close the valve in the event of a power failure
- Tight isolation up to 16 bar to ensure reliable operation
- Kvs values are similar to globe valves of the same size that do not require additional system design
System integrators
Your task is to design building management systems and optimally integrate field devices. Your goal is to reduce complexity and ensure transparency for the continuous optimisation of building technology. Belimo characterised control valves offer:
- Easy selection, mounting, and hassle-free service
- Tight isolation up to 16 bar to ensure reliable operation
- Combines the high isolation capabilities of a ball valve with a specialised disc that ensures an equal percentage flow characteristic to meet specification requirements
- MF models with on-site selectable control and feedback signal, and running time match design sequences and controller requirements
Building owners
Improvements in comfort and energy consumption as well as simple building expansions and upgrades are a constant challenge for you. Optimising your HVAC system with the least possible effort and low costs is in the main focus. Belimo characterised control valves offer:
- Characterised control valve technology prevents clogging due to debris and ensures flow is maintained in heating and cooling systems
- Tight isolation up to 14 bar ensures reliable operation
- Equal percentage flow characteristic provides optimal coil control
- Brushless DC motor technology offers accurate and quiet operation to maintain a comfortable building environment
Facility managers / Building maintenance
Management, control and operation of buildings and their technical equipment is part of your daily tasks. You seek solutions to ensure room comfort and optimise system operation. You value simple and transparent systems and, if necessary, quick delivery of spare parts and support available at all times. Belimo characterised control valves offer:
- 0% leakage rate for increased plant efficiency and building comfort
- Control with equal percentage valve characteristic curve prevents "hunting" of the control loop, increasing the life span of actuator and valve
- Characterised control valve technology prevents clogging due to debris and ensures flow is maintained in heating and cooling systems
- Easy selection, mounting, and maintenance for improvement projects or retrofits
- Fast delivery and online technology
