Zhenjiang pipeline pneumatic ball valve is corrosion resistant, heat resistant and aging resistant: Zhenjiang double flange valve connection is mainly used for loose sleeve connection of pumps, valves and other accessories. The double flange loose sleeve pneumatic ball valve is composed of loose sleeve expansion joint, short pipe flange, valve screw and other components. It can transmit the pressure thrust (blind plate force) of the connected parts and compensate the pipeline error, and cannot absorb the axial displacement.
Installation instructions for pipeline pneumatic ball valve, Tighten the gland bolts diagonally and evenly, and use them to form a whole with a certain displacement to facilitate installation and maintenance, and adjust according to the site size.
During operation, the reverse axial thrust can be transmitted to the whole pipeline. Scope of application of pipeline pneumatic ball valve: pipeline pneumatic ball valve is suitable for conveying seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and granular powder with temperature not higher than 250 degrees.
