The most intelligent butterfly valve on the market

The latest technology for butterfly valves from Belimo is especially designed for heating, ventilation and air-conditioning technology and fully meets all of its requirements. Butterfly valve/actuator combinations are available in DN 25 to DN 700 for 2-way open/close and modulating control applications, 3-way combinations for changeover and control applications from DN 150 to DN 300.

The Belimo advantage

Efficiency and reliability in versatile applications

Product range

8 reasons for using Belimo butterfly valves

1. Flexible utilisation options

2. Absolute seal integrity

3. Energy-saving design

4. Reduced weight and low installation height

5. Transparent communication

6. Seamless integration of sensors

7. High operating safety

8. Fit for reliable control tasks

Belimo Assistant App

With the Belimo Assistant App, the 2- or 3-way control butterfly valves as well as the 3-way changeover butterfly valves can be parametrised via Near Field Communication (NFC). NFC works without power and enables easy commissioning, parametrisation and maintenance directly from a smartphone.

Retrofit solutions for butterfly valves of other manufacturers

The Belimo retrofit product range includes universally applicable actuators to replace defective actuators or to motorise existing installations.

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.

  • Lower height compared to conventional solutions

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 butterfly valves offer:

  • Simplified commissioning via Near Field Communication (NFC)
  • Diagnostics and application data access with BACnet or Modbus
  • Flexible application thanks to multifunctional control (0.5...10 V, 2...10 V, BACnet, Modbus, MP-Bus), adjustable running time, fail-safe option and universal power supply from 24 to 240 V

Specialist wholesalers

For your customers you rely on high availability, easy selection and short delivery times for the products you offer. You require quick and easy access to information as well as comprehensive technical support from your suppliers. Belimo butterfly valves offer:

  • Flexible application thanks to multifunctional control (0.5...10 V, 2...10 V, BACnet, Modbus, MP-Bus), adjustable running time, fail-safe option and universal power supply from 24 to 240 V.
  • Lower maintenance cost with products engineered for HVAC applications and backed with a 5-year guarantee

Installers/plant engineers

The installation of HVAC building technology is your trade. To carry out your work, you need the right products at the right time on site. Easy mounting and expert support allow you to meet your tight schedule. Belimo butterfly valves offer:

  • Fast programming, commissioning and troubleshooting
  • Even when the actuator is not powered it can be programmed
  • Fast installation with accessible connection box for cable access, together with the control element assembly with two screws allows the valve unit to be quickly installed
  • Less commissioning effort with NFC and a smartphone – the Belimo Assistant App enables fast setup and troubleshooting
  • Easy troubleshooting with its unique position indication that can be viewed from long distances and at any angle

Building owners
