Pneumatic Butt-clamp Butterfly Valve

pneumatic butt-clamp butterfly valve, Flexible use of sophisticated J-ring and three eccentric multi-level metal seal structure, is widely used in medium temperature ≤ 425 °C of metallurgy, electric power, petrochemical, and municipal construction, drainage and industrial pipe,To regulate traffic and set stop body to use. The valve by three eccentric structure, valve seat and disc sealing surface plates are made of stainless steel with different hardness, good corrosion resistance, long life. The valves are two-way sealing function, the product line with national GB/T13927-92 valve pressure test standard. pneumatic butt-clamp butterfly valve, 1. The valve seal structure by three eccentric, valve seat and disc almost no wear, with the more functional view of the more tight seal. 2. Seals use stainless steel, with metal seal and the seal of the dual advantages of flexibility,both in the case of low and high temperature, all with excellent sealing properties, resistant to corrosion, long service life. 3. Dish plate sealing surface welding of cobalt-based alloy, sealing surface wear resistance, long service life. 4. Large size disc use a lattice structure, high strength, flow area, flow resistance small. 5. This valve has a bi-directional sealing capabilities, installation, media flow without restriction, but also from the impact of spatial location, can be installed in any direction.
