What are the differences between wafer type butterfly valve and flange type butterfly valve

2018-06-08

Preferred according to the different forms of connection, divided into two kinds of clip type and flange type, the transmission mode is manual, electric, pneumatic, electro-hydraulic and so on. There is also a difference in appearance.

wafer type butterfly valve

The wafer butterfly valve (the valve itself without flange) is to connect the valve between the two pipe flanges with stud bolts; the wafer butterfly valve is simple in structure, small in size, light in weight, and consists of only a few parts. And only need to rotate 90 ° to quickly open and close, simple operation, while the valve has good fluid control characteristics.

Flanged butterfly valve

Flanged butterfly valve is a valve with a flange, with bolts on both ends of the valve flange connected to the pipe flange. The sealing surface is wear-resistant and has a long service life. Unique structure, flexible operation, labor-saving, convenient, not affected by high and low medium pressure.

Flange type butterfly valve and wafer type butterfly valve is mainly used in oil, gas, chemical industry, water treatment, etc., generally in the industry has been widely used, can also be used in thermal power station cooling system.
