Characteristics of Butterfly Valve

1. The Butterfly Valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, quick switch, 90 reciprocating rotation, small driving Torque, etc. . It is used for cutting off, connecting and regulating the medium in the pipeline, it has good fluid control characteristics and sealing performance. 

2. The Butterfly Valve can transport mud and minimize the accumulation of liquid at the pipe mouth. Under low pressure, a good seal can be achieved. Good adjustability. 

3, Butterfly Plate streamline design, so that fluid resistance loss is small, can be described as an energy-saving products. 4. The valve stem is through-stem structure, after conditioning treatment, has good comprehensive mechanical properties and anti-corrosion, anti-abrasion. When the butterfly valve opens and closes, the valve stem only makes the rotation movement and does not make the lifting movement, the valve stem packing is not easy to destroy, the seal is reliable. Fixed with the taper pin of the butterfly plate, the extended end is designed to prevent punching out, so as to avoid the valve rod bursting out when the connecting place of the Valve Rod and the butterfly plate breaks accidentally.
