\nPneumatic butterfly valve is a rotary type control valve. It has the advantages of small size, light weight, and large rated flow coefficient, and is especially suitable for large diameter, large flow, concentrated turbid slurry or boiler kiln flue gas control.<\/span><\/span><\/span>
\nThis series of products has three types: standard, high temperature and sealed. The nominal pressure rating of the product is 0.1, 0.25, 0.6, 1.0MPa, the caliber is from 50mm to 1400mm, the leakage level is II and VI, and the flow characteristics are approximately equal percentage.<\/span><\/span><\/span>
\nWhen the pneumatic is switched to manual, the side-mounted handwheel mechanism method is used (Figure 3); Pull out the locating pin, pull the handle upwards, the worm gear engages with the worm, press the dowel pin, and rotate the handwheel to change the flow section. When manually switching to pneumatic, you can turn the handle instead.<\/span><\/span><\/span><\/p>\n
\n\u00a0\u00a0<\/span>The valve body is welded by steel plate, which is compact in structure, small in size and light in weight.<\/span><\/span><\/span>
\nZMAW and ZSCW products only have different actuators, and the others are the same, and the products are highly interchangeable.<\/span><\/span><\/span>
\nThe conversion ability between air-closed and air-open types is strong, and users can realize it on site.<\/span><\/span><\/span>
\nThe flow resistance is small and the rated flow coefficient is large, which is about 3 times that of single-seat valves of the same caliber.<\/span><\/span><\/span>
\n\u00a0\u00a0<\/span>The valve plate has an initial angle of 10\u00b0 when it is closed, so the leakage is small.<\/span><\/span><\/span>
\n\u00a0\u00a0<\/span>Sealed butterfly valves have a seat made of soft materials, so the leakage is small<\/span><\/span><\/span><\/p>\n

\na. Before installation, check whether the product model and specifications are consistent with the requirements of use, and then thoroughly clean the pipe to remove welding slag and debris.<\/span><\/span><\/span>
\nb. The valve should be installed upright and vertically on the horizontal pipeline, and should be supported and reinforced when the valve has a large self-weight or vibration.<\/span><\/span><\/span>
\nc. The installation site takes into account the safety of personnel and equipment, which is not only convenient for operation, but also conducive to disassembly and maintenance.<\/span><\/span><\/span>
\nd. The valve should be installed in the field where the ambient temperature is -30~60\u00b0C.<\/span><\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
