Pneumatic hard seal eccentric butterfly valve series products, long life, energy-efficient and butterfly valve. Its structure using the 3 d design of principle of heart valve seat adopt hard and soft sealing compatible multi-level structure, this product by the valve body, disc, the multi-level seat, Industrial Valves stem, drive mechanism and so on the main parts. Therefore is widely applied to metallurgy, electric power, petroleum, chemical, air, gas, combustible gas, as well as the corrosion medium such as water supply and drainage pipeline. Pneumatic hard seal eccentric butterfly valve structure of hard seal eccentric butterfly valve actuator 1, gear type double piston, output torque, small volume. 2, selection of cylinder aluminum alloy material, light weight, good appearance. 3, can be installed on the top and bottom manual operating mechanism. 4, the rack type connection adjustable opening Angle, rated flow. 5, actuators optional electric signal feedback instructions in order to realize automation and all kinds of accessories. 6, IS05211 standard connection provides convenience for the installation of the product replacement. Section 7, both ends of the screw can make the standard products in 0 & deg; And 90 & deg; Have & plusmn; 4° The adjustable range. Ensure the synchronization precision with the valve.
