Blue Butterfly Valve Flange

Butterfly valve flanges are called flanges, also known as flanged parts, and are a product that is interconnected with pipes in pipelines. The butterfly valve flange is roughly the same as the ordinary flange, the difference is the inner hole. The inner hole of the butterfly valve flange is smaller, and there is an extra slot for intubation.

The purpose of reducing the inner diameter of the butterfly valve flange is to match the size of the rubber sealing ring of the butterfly valve, so that the flange sealing surface and the rubber sealing ring are completely fitted, so compared with other conventional flat welding flanges, the sealing effect is better. Butterfly valve flanges are mainly used for butterfly valves with a diameter larger than DN50. Small-sized flanges are small in size, and the size that cannot be sealed can be ignored, which has little impact on the sealing effect.
