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. For the use as a 3-way changeover butterfly valve, the necessary parameters can be adjusted in just a few steps using the commissioning workflow. The adjusted parameters include setting the maximum position (opening angle) to 100% and the control to open/close, 3-point. The use as a 3-way changeover butterfly valve requires the commissioning of two devices. The control signal of the second actuator is automatically inverted using the commissioning workflow for parametrisation.
How-To: Commissioning 3-way control BFV
With the commissioning workflow for PR actuators, application-dependent, predefined settings can be selected easily and quickly and then written to the actuator. For the use as a 3-way control butterfly valve, the necessary parameters can be adjusted in just a few steps using the commissioning workflow. The adjusted parameters include the reduction of the maximum position (opening angle) to 60% and setting a linear characteristic curve to provide a constant mixing curve. The use as a 3-way control butterfly valve requires the commissioning of two devices. The control signal of the second actuator is automatically inverted using the commissioning workflow for parametrisation. The use as a 3-way control butterfly valve and a linear characteristic curve are only possible in combination with Belimo butterfly valves and are unsuitable for retrofit applications.
