Butterfly valve manufacturers tell you, what is the working principle of butterfly valve? The butterfly valve manufacturer tells you that the butterfly valve is a disk opening and closing thing that rotates about 90 degrees round trip to open, close or adjust the medium flow valve. Butterfly valve has simple structure, small size, light weight, small material consumption, small installation size, small driving torque, easy operation, fast speed, both flow regulation function and sealing function, is one of the rapidly developing valve varieties in the past ten years. Butterfly valves are widely used. The variety and quantity used are still expanding, and are developing to high temperature, high pressure, large caliber, high-density sealing, long life, good regulating characteristics and multi-functional valves. Stability and other performance indicators have reached a high level.

With the application of synthetic rubber to prevent chemical corrosion, the performance of butterfly valves has been improved. Synthetic rubber has the characteristics of corrosion resistance, corrosion resistance, dimensional stability, elasticity, convenient molding, cost reduction, etc. Synthetic rubber with different properties can be selected according to different use requirements to meet the use conditions of butterfly valve.

PTFE (PTFE) corrosion resistance, stable performance, not easy to aging, low friction coefficient, easy to form, stable size.

Butterfly valve manufacturers tell you that in order to meet the requirements of high and low temperature, strong erosion, long life and other industrial applications, metal sealed butterfly valves have been greatly developed. With the application of high temperature, low temperature resistance, steel corrosion resistance, steel corrosion resistance, high-strength alloy materials in butterfly valves, metal sealed butterfly valves have been widely used in high and low temperature, strong erosion, long life and other industrial fields, and large caliber (9 ~ 750mm) and high pressure (42.0MPa) have appeared.

Butterfly valve manufacturers tell you that after the butterfly valve is fully opened, the flow resistance is small. In the field of large diameter regulation, the application of butterfly valves is very common, because the opening is between 15 and 70, and sensitive flow control can be achieved.

The butterfly valve manufacturer tells you that the movement of the butterfly plate of the butterfly valve is wiped off, so most butterfly valves can be used for solid particles floating media. Depending on the strength of the seal, it can also be used for powder and granular media.

The butterfly valve manufacturer tells you that the butterfly valve is suitable for flow regulation. The pressure loss of the butterfly valve in the pipe is relatively large, about 3 times that of the gate valve, so when selecting the butterfly valve, the pipeline system should fully consider the influence of the pressure loss, and the strength of the butterfly valve plate subjected to the pressure of the pipeline medium should also be taken into account. In addition, it is necessary to consider the limitations of the operating temperature that the elastic valve material can withstand at high temperatures. The structure length and overall height of the butterfly valve are small, the opening and closing speed is fast, and the fluid control characteristics are good. The structure principle of butterfly valve is suitable for making large diameter valves. When butterfly valves are required to control flow, it is important to correctly select the specifications and types of butterfly valves so that they can work properly and effectively.
