Installation and maintenance of single flange pneumatic ball valve Single flange pneumatic ball valve is composed of pneumatic ball valve, short pipe flange, power transmission screw and other components. It can transmit the pressure thrust (blind plate force) of the connected parts and compensate for pipeline errors, and cannot absorb axial displacement. It is important for the connection of pumps, valves, pipelines and other accessories
。 Nominal diameter DN50-DN3200 Working pressure: 0.6-1.6MPA Medium: water, sewage. Sealing material: NBR, manufacturing standard: GB12465-2002.
Material: mainly Q235 carbon steel, stainless steel, cast steel, ductile iron, etc. Installation instructions for single flange pneumatic ball valve: the single flange pneumatic ball valve is applicable to the connection between one side and the flange, and the welding between the other side and the pipeline.
During installation, adjust the installation length between the two ends of the product and the pipeline or flange. After installation and welding, tighten the gland bolts diagonally and evenly to make them a whole. There is a certain displacement, which is convenient for installation and maintenance. It can be adjusted according to the site size. During operation, the axial thrust can be transmitted to the whole pipeline. Material of pneumatic ball valve: mainly Q235 carbon steel, stainless steel, cast steel, ductile iron, etc.
