Manual wafer metal sealing Butterfly Valve is suitable for medium such as water, air and natural gas. The leakage rate is in accordance with the standard of GB/T13927-92. The driving mode is manual, electric,pneumatic and hydraulic
- Compact structure, small volume, light weight, flexible operation, small opening and closing moment, labor saving and energy saving
- The three eccentric cone angle structure between the sealing pairs makes the two dense covers immediately detached from each other at the moment of opening of the butterfly valve to ensure that there is no friction between the sealing pairs.
- The triple eccentric structure between the sealing pairs makes the valve close more and more tightly, the seal is more reliable, the seal is non-leakage, and it has the function of bi-direction sealing.
- High temperature resistance, high pressure, corrosion resistance, long service life, enjoy the reputation of "the same life as the pipeline".
- When the sealing performance is reduced, the sealing performance can be restored if the sealing ring is close to the valve seat.
- When the working condition needs, the opening and closing angle of the butterfly valve can be adjusted, and then the flow rate can be adjusted.
The manual wafer type hard-sealing butterfly valve is a foreign advanced technology,and is widely used in the industrial pipelines such as the metallurgy, the electric power, the petrochemical industry, the water supply and drainage and the municipal construction of the medium temperature and the 425 DEG C by using the precise J-shaped elastic sealing ring and the tri-eccentric multi-levelmetal hard sealing structure, Used for regulating flow and carrying off fluid
The wafer hard sealed butterfly valve is mainly divided into manual wafer hard sealed butterfly valve, electric wafer hard sealed butterfly valve and electro-hydraulic wafer hard sealed butterfly valve, etc., which can be customized by users according to their needs.
