How to choose wafer butterfly valves?

A wafer butterfly valve is suitable for flow regulation. Due to the relatively large pressure loss of the wafer butterfly valve in the pipeline, the robustness of the butterfly plate to withstand the pressure of the pipeline medium when it is closed should also be considered. It is necessary to consider the limitation of the working temperature of the elastic valve seat material at high temperatures. When a wafer butterfly valve is needed to control the flow, the most important thing is to correctly select the size and type of the wafer butterfly valve.

What can wafer butterfly valves be divided into?

The turbine wafer butterfly valve uses a butterfly plate that rotates with the valve stem as an opening and closing part to realize the opening, closing and adjustment of the valve. Turbine wafer butterfly valve has excellent corrosion resistance, which can be applied to any concentration of acid, alkali, salt, oxidant, reducing agent and organic solvents. Turbine wafer butterfly valve can replace gate valves, globe valves and other types of cut-off and regulating valves.

The butterfly valve is clamped between the flanges at both ends of the pipeline, and then fixed with a set of bolts. The valve body of the pneumatic wafer butterfly valve is small in size and relatively thin in thickness. Pneumatic wafer butterfly valve is especially suitable for occasions where the distance between the two ends of the pipeline is short or the space is limited. Pneumatic wafer butterfly valves are divided into soft seals and metal seals according to different density structures. 

The electric wafer butterfly valve relies on the power drive of the electric actuator to control the opening and closing of the valve. The electric wafer butterfly valve has no flange, and the body is relatively thin. An electric wafer butterfly valve is especially suitable for working conditions where the site space is limited and the pipeline distance is relatively short. Due to the fact that the bolts will expand and cause leakage when the temperature is high, the wafer type electric butterfly valve is generally not recommended to be used in high temperature conditions.

How to choose wafer butterfly valves?

Determine the nature of the fluid in the pipeline, whether it is liquid, gas, or solid; whether it is neutral, corrosive, viscous, suspended particles, vacuum, high pressure, or powder. Then determine whether the function of the wafer butterfly valve requires only opening and closing, or whether it requires to control the flow accurately, or needs to reverse the flow.

From a functional point of view, wafer butterfly valves are more suitable for pipelines that need to control flow. Wafer butterfly valves are more suitable for open or closed pipelines because the flow path is straight, with small flow resistance and rapid opening and closing. 

From the nature of the fluid medium, wafer butterfly valve has a simple structure, opens and closes quickly, which is suitable for a variety of media, including media with suspended particles and powdered media. But wafer butterfly valve is not suitable for high temperature, high pressure and high tightness requirements. The flow rate adjustment range of wafer butterfly valve is small. 

Learn more about wafer butterfly valve can know the characteristics of the wafer butterfly valve and how to choose the right wafer butterfly valve. In the process of butterfly valve development, a number of very powerful companies have emerged, such as Tianjin Worlds Valve Co., Ltd. Our company knows how to innovate while developing, and will also go out in the process of introducing a wafer butterfly valve.
