The Metryva Chuanyi MTVVB400 Four-Eccentric High-Performance Butterfly Valve is engineered for applications requiring precise flow control and reliable sealing under demanding conditions. Its innovative four-eccentric design ensures minimal friction during operation, enhancing durability and performance.
Four-Eccentric Structure: The valve incorporates a conical sealing surface with an angular offset on the horizontal centerline, and the rotational axis is offset both axially and radially from the flow path center. Additionally, the elliptical sealing cross-section's minor axis is designed as a perfect circle. This configuration ensures frictionless engagement and disengagement of the sealing surfaces during opening and closing, resulting in automatic alignment and tight sealing.
Enhanced Flow Capacity: The circular cross-section of the sealing pair allows for greater flow capacity compared to traditional designs.
Reduced Radial Offset: Minimizes unbalanced forces exerted by the medium on the valve disc, improving bidirectional sealing performance.
Durable Sealing Surfaces: The valve seat's sealing surface is overlaid with high-strength, corrosion-resistant alloys, ensuring long-term reliability and extended service life.
High-Strength Construction: Utilizes high-strength stainless steel materials and an integrated valve stem design, enabling the valve to withstand significant differential pressures.
