Butterfly valve installed in reverse
Thread Content
Will installing a butterfly valve in reverse affect the flow rate of the medium?
It depends on the specific structure; analysis is possible only with structural drawings
Butterfly valves are generally full-bore, so there should be no requirements, unless the process has special needs such as sealing
Generally, butterfly valves do not have a direction of installation, unless there are special requirements
Conventional centerline butterfly valves have no orientation requirement; they can be installed in either direction without affecting flow rate. Dual eccentric and triple eccentric types are distinguished by directionality, and must be installed with the correct orientation. This does not affect flow rate, but rather the sealing
Butterfly valves should not have a direction for installation
It has little impact on traffic, so it can be ignored; it might not be able to be shut down completely
