The butterfly valve is a valve that opens and closes and closes the fluid passage by reciprocating about 90° with a disc type opening and closing member. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate, and quick, and also has good flow adjustment function and closed sealing performance, and is made of different materials. The butterfly valve can also be applied to various corrosive medium pipelines, and is one of the fastest growing valve varieties in the past decade.
The advantage of Butterfly Valve
Butterfly valves are most often used to regulate the flow of gases, liquids, or slurries. Because they can be designed with reference to specific pressure requirements and usage patterns, their applications are very broad. Some of the more common include:
1, easy to open and close, labor-saving, small fluid resistance, can be operated frequently.
2, simple structure, small size, short structure length, small size, light weight, suitable for large diameter valves.
3, the mud can be transported, and the liquid is accumulated at the mouth of the pipe at least.
4, under low pressure, can achieve a good seal.
5, the adjustment performance is good.
6, the valve seat channel has a large effective flow area and a small fluid resistance.
7, the opening and closing torque is small, because the butterfly plates on both sides of the rotating shaft are basically equal to the medium, and the direction of the torque is opposite, so the opening and closing is more labor-saving.
8, the sealing surface material is generally made of rubber or plastic, so the low-pressure sealing performance is good.
9, easy to install.
10, the operation is flexible and labor-saving, you can choose manual, electric, pneumatic, hydraulic.
