Product Introduction
Introduction:
Butt welding type triple eccentric hard seal butterfly valve adopts turbine drive, which is easy to operate and has self-locking function. It applies advanced triple eccentric structure design (radial eccentricity, axial eccentricity and angular eccentricity), and is processed and manufactured with advanced technology and special process equipment, which can ensure the accuracy of parts and assembly. It ensures that all conical surfaces of the seal are consistent and completely eliminates temperature interference and wear on the sealing surface. Therefore, its switching resistance is small, the sealing is reliable, the sealing surface wear is small, and the machine has a long service life.
Application:
The butt welding type triple eccentric hard seal butterfly valve is widely used in metallurgy, petrochemical, chemical, oil refining, water supply and drainage engineering and other industries.
Description:
Butt welding type triple eccentric hard seal 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. It adopt three-dimensional eccentric elastic or multi-level hard sealing structure, and 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
