The soft-sealing double eccentric flanged butterfly valve, also known as the valve, is a type of valve that is commonly used in various industries. It is designed with a soft sealing mechanism that ensures tight closure and minimizes leakage. The double eccentric design enables the valve disc to move away from the seat before rotating, reducing friction and wear. This design also helps to achieve a bubble-tight shut-off, making it highly reliable and efficient.

The flanged connection of the valve allows for easy installation and maintenance. It can be quickly and securely connected to the pipeline using bolts and nuts. The valve is also equipped with a butterfly-shaped disc that is attached to a stem.

Product Description:

This butterfly valve is the latest soft-sealed eccentric flange butterfly valve developed by our company. It is mainly used for water supply and drainage in water plants, power plants, steel smelting, papermaking, chemical industry, water source engineering, environmental facility construction, etc., especially for water pipelines. Regulating and shut-off devices are used.

Features:

1. Reasonable design, compact structure, easy assembly and disassembly, and easy maintenance;

2. The eccentric structure is adopted to reduce the friction of the sealing ring and prolong the service life of the valve;

3. The sealing ring of the valve plate adopts a "T" shape structure, and the sealing pair is linearly sealed;

4. Completely sealed, zero leakage;

5. Replacement of valve plate sealing ring, "O" ring, butterfly plate, rotating shaft and other materials can be applied to various media and different temperatures.

Executive standard:

1. Meet the standard of GB/T12238-89 "General Valve Flange and Wafer Connection Butterfly Valve".

2. The test conforms to the standard of GB/T13927-92 "General Valve Pressure Test".

3. The side flange connection complies with the standard of GB/T9119 "Integral Cast Iron Pipe Flange". At the same time comply with BS4504, ISO20284, DIN2501 in PN1.0MPa, PN1.6MPa flange connection.
