Performance Specifications/purposes And Characteritics
This buttrfly valve is suitable for opening and closing or regulating medium on pipelines with high temperature, high pressure, fire prevention, insulation, etc.
Its main characteristics are as follows:
1. Compact structure, small size, light weight, flexible operation, and convenient use;
2. Adopting a three-dimensional eccentric hard hiting or muli-level hard sealing structure, its sealing performance is reliable and reaches zero leakage;
3. This valve has no flange, which brings great convenience and aesthetics to the insulation and wrapping of pipelines;
4. It has characteristics such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance.
Drive System
Warm gear transmission, pneumatic transmission, electric transmission,hydraulic transmission.
