How to install a PR butterfly valve actuator
Butterfly valve assembly with communicative PR actuator.
Butterfly valves and actuators
The butterfly valves and the PR actuators are the most intelligent, energy efficient and reliable high flow solution in the HVAC market. Having focused on ease of installation, application flexibility and longevity, this series sets new performance standards in HVAC industry.
Butterfly valves for control applications
Belimo's advanced butterfly valve design and the harmonisation of butterfly valve and intelligent actuator result in a control valve with significant advantages.
How-To: Commissioning 3-way Changeover BFV
With the commissioning workflow for PR actuators, application-dependent, predefined settings can be selected easily and quickly and then written to the actuator.
