feature
1. Triple eccentric sealing structure: adopting a composite design of eccentricity between the valve stem axis and the sealing surface, eccentricity between the valve stem axis and the pipeline axis, and eccentricity of the sealing surface cone angle, achieving frictionless opening and closing of the butterfly plate throughout the entire process, with a hard metal contact of the sealing pair, reliable sealing, and long service life.
2. Bidirectional metal hard seal: The butterfly plate and the welded hard alloy valve seat form a wedge-shaped compression seal, which can withstand high pressure, high temperature, and corrosive media, and is suitable for bidirectional flow conditions.
3. High welding connection strength: The valve body is directly welded to the pipeline, with high connection strength and absolutely reliable sealing, suitable for high-pressure pipelines and flammable, explosive, and toxic medium systems.
4. Small opening and closing torque, easy operation: The eccentric structure reduces friction, and the 90 ° rotation operation torque is small, which can be adapted to various driving modes such as manual, electric, and pneumatic.
5. Excellent resistance to high temperature and high pressure: The metal hard seal structure can adapt to high temperatures and higher pressures (such as PN16~PN100 or higher) up to 600 ℃, with stable performance.
6. Long service life and easy maintenance: The sealing surface is wear-resistant and corrosion-resistant, and there is no friction or wear during the opening and closing process. After long-term use, the sealing performance can still be maintained, and the maintenance cycle is long.
7. Widely applicable in various fields: suitable for high temperature, high pressure, corrosive medium pipelines in industries such as petroleum, chemical, power, metallurgy, etc., especially suitable for cutting and regulating under harsh working conditions.
