- Nov 11, 2017 -

Butterfly Valve's butterfly plate is installed in the diameter direction of the pipe. Butterfly valve structure Simple, small size, light weight. It is made up of only a few parts, and it can be quickly and easily operated simply by rotating 90°, and the valve has good fluid control characteristics. Butterfly valve is in full open position, the butterfly plate thickness is the medium flow through the valve body when the only resistance, so through the valve produced by the pressure drop is very small, it has a good flow control characteristics.

If the butterfly valve is required to be used as flow control, the main thing is to select the correct size and type of valve. The structure principle of the butterfly valve is especially suitable for making large caliber valves. Commonly used butterfly valve has pair of butterfly valve and flange type butterfly valve two kinds. The wafer-type butterfly valve is connected with a double head bolt to the valve between two pipe flanges, the flanged butterfly valve is provided with a flange on the valve and the flange is connected with the flange of the valve on the pipe flange.

The butterfly valve is used in many fields, such as petroleum, chemical industry, metallurgy, hydropower and so on, as a component which realizes the pipeline system's On-off and flow control. In the well-known butterfly valve technology, the sealing form of the sealing structure, sealing material for rubber, PTFE and so on.
