The Precision Casting Butterfly Valve is a simple regulator valve that can also be used for switching control of low pressure piping media. Ventilation butterfly valve is a kind of non-closed butterfly valve. It is used in the dusty cold air or hot air gas pipeline of ventilation, environmental protection engineering in chemical industry, building materials, power station, glass and other industries. It is used as a gas medium to regulate the flow or cut off the pipeline control device. This type of valve should generally be installed horizontally in the pipeline.

Precision Casting Butterfly Valve is designed and manufactured with a new structure of medium-line disc and short-structure steel plate. It is compact, light in weight, easy to install, low in flow resistance, large in flow, avoids the effects of high temperature expansion, and is light in operation. No connecting rods, bolts, etc., reliable operation and long service life. It supports multi-station installation and is not affected by media flow.
