The butterfly valve is suitable for use in high temperature, high pressure, fire prevention, thermal insulation and other pipelines for opening and closing or regulating media. Its main features are as follows:
1, compact structure, small size, light weight, flexible operation, easy to use;
2, using three-dimensional eccentric elastic or multi-layer hard seal structure, its reliable sealing performance to achieve zero leakage;
3, this valve can not be blue, brings great convenience and appearance to the pipeline and insulation and dressing;
4, with high temperature, high pressure, corrosion resistance, wear and other characteristics.
Drive type: worm gear drive, pneumatic drive, electric drive.
