Efficient in every way

Belimo ZoneTight™ valves are engineered for maximum efficiency in tight spaces and set new performance standards for both pressure-dependent and pressure-independent zone applications.

The QCV, PIQCV and PIFLV valve-actuator combinations consume 95% less current than conventional zone valves. Impressive tool-free mounting (actuator with valve) simplifies commissioning and reduces labour costs.

Belimo ZoneTight™ control valves ensure permanent and precise control of hydronic systems.

HVAC hydronics – the goldmine in building renovation projects.

HVAC hydronic system

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.

No leakage

Super compact and versatile

belimo_pi-application_rgb_960x540px

The tight-closing characterised control valve prevents internal leakage in the closed state and thus unwanted consumption at zero load. The self-cleaning effect prevents sticking. Activation of the chilling or heating power is reliable and only in case of need.

The ZoneTight™ characterised control valve guarantees equal percentage flow characteristics. The stability of control achieved in this manner reliably reduces the tendency of the chilling or heating system to oscillate. This ensures that optimum comfort with the least possible use of energy is achieved.

Customer-specific products

Customising a Belimo product

Custom-made products. Less effort, more profit.

These days, challenges in planning and on the construction site are difficult to solve using standard products, which is why pre-manufactured products 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.
