Because the movement of the butterfly valve plate is wiping, most butterfly valves can be used for media with suspended solid particles, and can also be used for powdery and granular media according to the strength of the seals.
The structural length and overall height of the butterfly valve are small, and the opening and closing speed is fast. When the valve is fully opened, it has small fluid resistance. When the valve is opened to about 15 ° to 70 °, it can also perform sensitive flow control. The structural principle of the butterfly valve is more suitable for making large diameter valves.
Stainless steel low temperature is applicable to various pipelines of DN50 ～ DN2000 and PN6 ～ PN40, and is used to cut off or connect the medium in the pipeline. With different materials, the butterfly valve can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media. The drive mode of butterfly valve is manual, worm gear drive, pneumatic or electric. Butterfly valves are generally connected by flanges or butt welding. Weld the butterfly valve flange on both ends of the pipe (the nominal pressure rating of the flange shall be the same as that of the butterfly valve), and then use bolts to pass through the four ear holes of the butterfly valve and fix it on the flange, and use bolts to fix both sides. This butterfly valve is a wafer type butterfly valve.
