1.Application
The centerline butterfly is mainly used for regulating the flow rate and storage medium of water supply and drainage, gas pipelines in food, medicine, chemical, petroleum, and other industries
2.Structure Features
·Lightweight structure, flexible operation, and quick opening and closing;
·The inner surface of the flow channel is smooth, with low fluid resistance and high flow capacity;
·Multiple sealing materials are available to ensure reliable sealing and corrosion resistance under different working conditions:
·High precision butterfly plate edge sealing surface, achieving bidirectional sealing with zero leakage and extending the service life of the valve seat sealing ring:
·The frame support design and valve body lining design are respectively adopted for the clamp type and flange type center line butterfly valve seat seals to prevent leakage caused by the seal falling off or moving:
·The combination design of the stem sleeve support and O-ring seal can effectively reduce the opening and closing torque and the wear of the stem, ensuring a more reliable seal:
·The elastic sealing ring of the valve seat extends to both ends of the valve body, and does not require flange gaskets during installation. It can be directly installed and used with companion flanges:
·According to user requirements, electric, pneumatic, hydraulic, and electro-hydraulic actuators can be selected to achieve remote control and automated operation.
