Double flanged butterfly valve manufacturer in USA
A Double flanged butterfly valve's body has two flanges, one on the upstream end and the other on the downstream end. This type of butterfly valve, which is used to monitor, regulate, and throttle flow, is the most reliable seated valve design for dead-end operation. A double-flanged butterfly valve is easier to set up than a lug or wafer type, and it has a stronger mechanical construction, making it excellent for heavy-duty, large flow-handling applications.
