U型双法兰        双法兰1

Double-flanges butterfly valve is very common, it has two different kinds , now i want to share a little knowledge about

butterfly valve as following:

Figure A is ” U” type double -flanges butterfly valve .

Figure B is double-flanges butterfly valve . 

Both of them have double flanges , but their connection type is different. The two pictures show the difference for two kinds of double-flanges butterfly valve evidently .

The face-to-face of  Type A is shorter , and the weight is lighter, it is made with a big diameter usually. 

Type A can be used to transport mud , because of it’s short face-to-face , the mud is  remained less  through the valve.

So if you make a order about butterfly valve , please notice it .
