Shaanxi dust hopper discharge manual butterfly cement silo unloader valve manually Synonyms: Powder butterfly Connection: Flange, material: cast aluminum, nominal diameter: 100-350 (mm), drive media: air, Pressure Range: 0.2Mpa, suitable temperature: up to 80 ℃, the main material: half body is aluminum alloy rotary valve wear-resistant polymer material, the structure forms: vertical plate, transmission forms: pneumatic, manual sealed form: soft sealing type, pneumatic actuator configuration: CP101, CP126 model. Cement silo unloader valve manually by using gravity casting made of two half-body composition, half body aluminum alloy material, the rotary valve plate using polymer materials, has a good seal. Top and bottom of the same circular flange, having a top flange and a hemming member for a flexible sleeve. Cement silo unloader valve manually double flanged butterfly valve with two identical flange; while the lower single flange butterfly valve is equipped with a connecting ring extending to install sleeving. Depending on the application requirements, you can handle alone drive or optional cylinder drive kit. Industrial design with the use of a special composite material to make the butterfly valve has a compact and lightweight structure, miserable plate wear, long seal life, easy installation and maintenance, etc., is a cost - highly effective powder valve. Cement silo unloader valve manually with a compact and lightweight construction make silos, misery plate wear, sealed long life, easy installation and maintenance, etc., is a cost - highly effective powder special butterfly switch is mainly used for bins, hoppers and silos equipped with powdery or granular materials. Cement silo unloader valve is manually closed parts (valve or disc) to the disc around the valve axis to achieve the opening and closing a valve in the main pipeline from the off and throttling. Butterfly is a disc-shaped opening and closing parts of the disc, in the valve body rotating around its own axis, so as to achieve the purpose of opening and closing or adjusting. Valve fully open to fully closed is usually less than 90 °, butterfly and butterfly stroke itself is not self-locking capability, in order to position the disc to install the worm gear on the stem. Aluminum alloy body, steel valve plate, BNR rubber seals, covered with wear-resistant polymer materials processing. Manually cement silo unloader valve is the company developed specifically for powder, granular materials for industrial products. Die-cast body is made of lightweight aluminum alloy, the disc is lined with wear-resistant steel core polymer material, soft and wear-resistant rubber ring seal makes it ideal for the formation of the various benefits of powder, granular materials applications, especially for highly abrasive materials. Shaanxi dust hopper discharge manual butterfly Performance - Features - Benefits valve with top flange and folding parts, suitable for connecting a flexible sleeve valve, the top and bottom of the flange to the same maximum withstand pressure 0.2bar (2.9PSI ) semi-high-pressure die-cast body, half body aluminum alloy material. Shaanxi dust hopper discharge valve is mainly used to manually switch bins, hoppers and silos equipped with powdery or granular materials. Can be applied to deal with all powdery and granular materials, the use of the material itself gravity valve closure and pneumatic transport of dry materials. Can be installed below the hopper, bin, silo, spiral or other type of conveyor, and connecting the pneumatic conveying line. Because of the special structure and the use of this valve engineering materials, it is always a very economical and very efficient choice.
