Installation Method Of Pneumatic Ball Valve

The installation method of the pneumatic ball valve, through the presentation of the installation steps, can give some references to friends who actually install and operate it. In view of the different working conditions, the pre-installation preparations and actual installation methods are roughly listed for reference. The actual working conditions are the main focus, and the details can be foolproof.

Precautions before installation

The pipelines before and after the pneumatic ball valve are ready. The front and rear pipes should be coaxial, and the sealing surfaces of the two flanges should be parallel. The piping should be able to bear the weight of the ball valve, otherwise, proper support must be provided on the piping. Clean the pipeline before and after the valve to remove oil, welding slag, and all other impurities in the pipeline; check the signs of the pneumatic ball valve to find out that the ball valve is intact. Fully open and fully close the valve several times to confirm that it works normally; remove the protective parts on the connecting flanges at both ends of the pneumatic ball valve; check the valve hole to remove possible dirt, and then clean the valve hole. Even tiny particles of foreign matter between the seat and the ball may damage the seat sealing surface.

installation method

Put the valve on the line. Either end of the valve can be installed on the upstream end. Valves actuated by handles can be installed anywhere on the pipeline. However, ball valves with gearboxes or pneumatic drivers should be installed upright, that is, installed on horizontal pipes, and the driving device is above the pipes; a gasket should be installed between the valve flange and the pipeline flange according to the pipeline design requirements; The bolts need to be tightened symmetrically, sequentially and evenly; connect the pneumatic pipeline.
