Introduction:
Butt-welding butterfly valve adopts turbine drive, easy to operate and has self-locking function. The application of advanced three-eccentric structure design (radial eccentric, axial eccentric and angular eccentric), the use of advanced technology and special technology equipment processing and manufacturing, to ensure the precision of parts and assembly precision. Ensure that all conical surfaces of the seal are consistent, and completely eliminate the temperature interference and wear of the sealing surface. Therefore, the switch resistance is small, reliable sealing, sealing surface wear is small, the machine long working life.
Application:
The product is widely used in metallurgy, petrochemical, chemical, oil refining, water supply and drainage engineering and other industries.
Description:
Welding type three eccentric sealing butterfly valve is suitable for high temperature, high pressure, fire prevention, heat preservation and other pipelines as after closing or adjusting medium.
Main features:
1. Compact structure, small size, light weight, flexible operation, easy to use;
2. Adopt three-dimensional eccentric elastic or multi-level hard sealing structure, its sealing performance is reliable to achieve zero leakage;
3. This valve has no flange, which brings great convenience and beauty to the thermal insulation of the pipeline.
4. High temperature, high pressure, corrosion resistance, wear resistance and other characteristics
