Details
The electric double-flange butterfly valve features a new structural design, combining a centerline-type disc with a short, structurally reinforced steel plate welded together. It boasts a compact design, lightweight construction, easy installation, minimal flow resistance, and high flow capacity. Additionally, it effectively avoids the impact of thermal expansion while ensuring smooth, effortless operation. The valve has no internal linkages or bolts, making it highly reliable and durable with an extended service life. Moreover, it can be installed in multiple positions without being affected by the direction of the media flow.
Main features of the electric double-flange butterfly valve product
1. Even under high-temperature and high-pressure conditions, it maintains stable sealing performance. Its unique sealing system ensures excellent sealing capabilities across a wide temperature range—from ultra-low to ultra-high temperatures.
2. The three-dimensional eccentric sealing system, combined with an optimized design, ensures minimal resistance when the valve is opened. The sealing surface of the butterfly disc features an upwardly convex conical shape; during opening, all points on the disc’s circumferential surface simultaneously disengage from the sealing ring, preventing solid particles from easily accumulating on the sealing area. The valve closure process relies on the elastic compression of the sealing ring to achieve a tight seal.
3. There is no jamming phenomenon between the butterfly plate and the sealing ring.
4. The sealing performance of the valve is unaffected by temperature changes.
5. Graphite is used to create a compression-molded sealing ring. As described above, this ensures zero leakage—combining metal sealing with the added advantage of maintaining zero leakage before, during, and after a fire—making it inherently fire-safe.
