Efficiency and Reliability in Versatile Applications

Thanks to their reliability, flexibility and energy efficiency, many customers have become devotees of Belimo butterfly valves and PR actuators since they were launched in November 2016. The butterfly valve-actuator combinations have already been able to prove themselves in projects such as the new chiller of the SwissCo AG pharmacy group, the heating system of the Kuhn Champignon AG food manufacturing company or as a retrofit solution in the cooling plant of the Müller Produktion GmbH installation company. Thanks to their communication capability, the actuators were readily integrated in the existing systems, commissioned or configured in just a few minutes, providing information regarding their operating status. In combination with the specially developed butterfly valves, they ensure optimum performance and contribute towards reducing energy consumption.

The Latest Technology for Butterfly Valves

In the Heating, Ventilation and Air Conditioning Industry (HVAC), butterfly valves are fundamental components in virtually every hydronic system. Most butterfly valves available on the market are less than ideal for this field of application – they leak, their running times are not optimised for HVAC applications, they are too big and heavy for easy installation and they cannot be commissioned quickly in the field. However, the tried and trusted Belimo butterfly valves are the exception here. The latest technology for butterfly valves from Belimo is especially designed for the Heating, Ventilation and Air Conditioning industry and fully meets all of its requirements. Belimo is setting new standards here :

• Innovative

Butterfly valves from Belimo are ideally suited for open/ close, changeover and control applications. The actuator and the valve design allow a reduction in investment costs as well as energy savings of up to 80 %. Intelligent self-adjusting end stops ensure that they are easy to mount and commission.

• User – Friendly

Optimised mechanical design and easy installation are possible due to the reduced height and weight of the actuator. Flexible visual position indication and the NFC capability enable fast installation, good visibility of the valve position, as well as easy commissioning and troubleshooting – even when the actuator is not connected to the power supply.

• Reliable

Thanks to the 5-year warranty, Belimo is the best choice for your application. Backed with more than 40 years of design experience, the newly designed butterfly valves and PR actuator with its long-life brushless DC motor are perfectly coordinated with one another.

Flexible for every application

Belimo butterfly valves can be used universally as tight-closing 2-way and 3-way valves for open/close, changeover, and control applications (as mixing and diverting valves). This flexibility is guaranteed by the energy-efficient and multifunctional PR actuators.

• 100% Tight for Cooling and Heating Generation

The Belimo wafer-type or lug-type butterfly valves are tried and trusted, tight-closing devices – with up to 14 bar closing pressure (leakage rate A, tight). In addition to motorisation with Belimo rotary actuators, the butterfl y valve is also available with lever or worm gear.

• Flexible Field Applications

Butterfly valves can be installed anywhere in the pipe. With the 3-way butterfly valve, the installation on the T-piece can be executed in any way, making the product universally suitable for changeover and control applications and also can be used without restriction as either a mixing valve or a diverting valve.

• Fit for Reliable Control Tasks

The Belimo butterfl y valves have a virtually equal-percentage characteristic curve for opening angles between 0 and 60 %. Depending on the desired kv value, the opening angle can be set via NFC with the Belimo Assistant App on a smartphone. For butterfly valve combinations with the PR actuator, the flow characteristic can be set to equal-percentage or linear. Combining two 2-way butterfly valves with a linearly parameterised characteristic curve into a 3-way butterfl y valve results in a perfect mixing characteristic curve. Which means that Belimo butterfl y valves are ideally suited for use as control device in 2-way and 3-way-applications.

• Transparent communication

The butterfly valve actuators can be confi gured using the Belimo Assistant App, which means that the control, running time and maximum opening angle of the butterfly valve can be set for each application. Key performance indicators reveal the state of health of the actuator to guarantee reliable operation.
