Selection of pneumatically adjustable butterfly valves
Thread Content
Which are the good manufacturers of pneumatically adjustable butterfly valves? Are there any selection guides available?
I’ve used Fisher’s and Samson’s. . The former is a bit expensive, but it has worked fine in the workshop for 10 years with almost no problems. The latter costs half as much as the former, and no negative effects have been observed. .
There are also the well-known Teco butterfly valves~~~~
Those are all imported; domestic products can actually meet the requirements as well. I work on control valves
Our butterfly valve series are quite well-known in China; feel free to come and inquire
