Hi all,
I posted this on the valve engineering board and thought I might get some good information here as well.
I am working on updating our specifications for plug valves for sewage treatment and have a question. There seems to be two main types of plug valves, rectangular ported and round ported. I have heard that round ports are better for plug valves because the head loss is less, and I have heard that rectangular ports are better because they have better sealing characteristics. In addition, to get a full port size with a rectangular shaped port, you have to go one size larger.
Can I ask which type of plug valve you all prefer, and why? Are there other characteristics of a plug valve that are more important than port shape that I want to be sure and include in my specs?
Thanks for any guidance you can provide.
