DN 400 PN 10 Fire Grey Cast Iron Flanged Butterfly Valve With Handwheels
Flanged Butterfly Valve Introduction
The flanged butterfly valve is the fastest-growing type of valve in the near future. It has the characteristics of simple structure, small volume, light weight, less material consumption, small installation size, quick opening and closing, 90-degree reciprocating rotation and small driving torque.
It is used to cut off, connect and adjust the medium in the pipeline, and has good fluid control characteristics and closing and sealing performance.
The streamlined design of the butterfly plate reduces the fluid resistance, which is an energy-saving product.

Characteristics
※ Compared with other valves of the same specification and pressure grade, the flanged butterfly valve has the advantages of short structure length, small size, light weight and simple structure.
※ Quick opening and closing, easy operation, and can be used for quick opening and closing of valves.
※ It has good flow regulating function and closing tightness, long service life, and can be used as regulating valve.
※ It is suitable for large-diameter valves and widely used in large water supply and drainage pipelines.
Storage and Maintenance Cautions
- When not in use, it should be placed in a dry and ventilated room, and both ends should be covered with dust covers to ensure that the inner cavity of the valve is clean.
- When stored outdoors for safekeeping, it should be supported, not in contact with the ground, and covered with plastic film for protection.
- When the valve stored for a long time is reused, check whether the packing fails, and add lubricating oil to each rotating part.
- During use, the valve should be checked regularly to ensure its normal use, including tightening the valve packing gland nut regularly to compensate the valve stem wear.
- The valve must be used and maintained within the specified service period, including replacement of gasket, packing, sealing ring, ball (as required) and other sealing pairs.
- Keeping the working environment of the valve clean can prolong the service life of the valve.
