DELCO Manual Metal Hard Seal Wafer Butterfly Valve, High Temp Wear Resistant Valve for Steam Industrial Pipeline Control

Manual wafer type hard seal butterfly

valve is suitable for water, air, natural gas and other media, the leakage rate is in line with GB/T13927-92 standard, the driving mode is manual, electric, pneumatic, hydraulic.

1. Compact structure, small size, light weight, flexible operation, small opening and closing torque, labor saving and energy saving.

2. The three-eccentric cone angle structure between the sealing pairs makes the two sealing surfaces immediately separate from each other at the moment of opening of the butterfly valve, ensuring that there is no friction between the sealing pairs.

3. The three-eccentric structure between the sealing pair makes the valve more closed and tighter when it is closed, the seal is more reliable, no leakage is achieved, and it has a two-way sealing function.

4, high temperature resistance, high pressure, corrosion resistance, long service life, enjoy the reputation of "the same life with the pipeline.

5. It has sealing adjustment performance. When the sealing performance decreases, the sealing ring can be closed to the valve seat to restore the sealing performance.

6. When the working conditions require, the opening and closing angle of the butterfly valve is adjusted to adjust the flow.

Manual wafer type hard seal butterfly valve adopts foreign advanced technology, with precision J-shaped elastic sealing ring and three eccentric multi-level metal hard seal structure. It is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃ to adjust flow and carry off fluid.

The wafer type hard seal butterfly valve is mainly divided into: manual wafer type hard seal butterfly valve, electric wafer type hard seal butterfly valve and electro-hydraulic wafer type hard seal butterfly valve, etc., users can customize according to their needs.
