Butterfly valve types

by Butterflyvalve Valteccn Butterfly valve supplier and manufacturer

A distinct feature of a butterfly valve is it can cope with high-pressure recovery, but can only accommodate low-pressure drops. This is true especially when it’s function is to handle large amounts of liquids or gases at low pressure differentials, such as in a hydroelectric power plant MIV system. Hence, depending on your application, it need not be opened more than 60 or 70 angular degrees from its closed position.

Overall, you can use butterfly valves in a wide variety of industrial applications for throttling, flow control, and pressure control purposes. You may also choose from sizes 2 to 60 in.
