Product Description

Simple Description of U Section Butterfly Valve:

U-shaped butterfly valve is a wafer type valve with two flange ends. Unlike traditional double flange butterfly valves, although two integral flanges are cast as a whole on the valve body, the internal space between the two integral flanges is too small to be connected to the pipe flange bolts on both sides separately, and the structural length of the two end faces is relatively smaller. Therefore, when it is installed between two pipeline flanges, it needs to be connected by bolts. The cross-sectional view of this valve is similar to the capital letter "U", hence it is called a U-shaped section butterfly valve.

Design characteristics of U-shaped butterfly valve:

-Concentric disc design: Align the centerline with the centerline of the shaft.
-Pinned valve disc: By using a tapered pin, torque is transmitted from the shaft to the valve disc.
-Suitable for larger sizes: usually suitable for sizes 12 inches and above.
-Lightweight, easy to install, and high cost performance.
-It can be used not only for switch services in pipelines, but also for pipeline end services. End of pipe service refers to the situation that occurs when the downstream side of the valve opens to the atmosphere.
-ISO 5211 mounting flanges can be used to connect various manual or automatic operating devices.
