butterfly valve (Pneumatic/Electric)

butterfly valve Introduction

A butterfly valve, also called a flap valve, is a kind of regulating valves which has a simple structure. The closure member of the butterfly valve is a disc, which revolves around the valve shaft to open or close.
The butterfly valve has a lot of types. Based on the sealing materials, the butterfly valve can be classified into a soft seal butterfly valve and a hard seal butterfly valve.
