, achieve complete sealing, and the gas test leakage is zero.
》Usage Precautions
The butterfly valve can be installed on the pipeline at any position in the space.
The installation position of this butterfly valve should ensure the convenience of use, maintenance and replacement.

》Operation Instructions of Grooved Butterfly Valve
Grooved butterfly valve is used to control solid materials. It is often used as a discharge valve at the bottom of the tank, such as the bottom of cement tanks, stone powder tanks, etc. Used for feeding and quick cutting. Because dust materials mostly contain large or small particles, there is no doubt that they will wear the valve sealing surface. Improper selection will greatly reduce the service life of the valve, or quickly cause internal leakage of the valve, affecting its continued use.
The grooved butterfly valve is designed using advanced foreign technology and many improvements made by our company. It is made of carbon steel as the main material, the valve body is welded with thick-walled seamless pipes, and the valve plate is made of ductile iron. It has reliable quality, is stronger and more durable than cast iron, has a more beautiful appearance, is more affordable, and has the ability to connect with pipe fittings. The desired speed. It can be widely used in water supply and drainage, fire protection, petroleum, chemical industry, medicine, steel and other pipelines for cutting or regulating.
