Pneumatic ball valve installation instructions

, pneumatic ball valve before and after the line has been ready. Before and after the pipe shall be concentric, two flange sealing surface should be parallel. Pipe should be able to withstand the weight of the pneumatic valve, ball or piping must be equipped with appropriate support.
sweep, blow the pipeline before and after pneumatic valve, oil, remove the pipe welding slag, and all other impurities.
, check the pneumatic ball valve, pneumatic ball valve is in good condition. The pneumatic valve fully open full closed several times to confirm they work.
, down the ball on the other side of pneumatic valve protection on the connecting flange.
remove potentially some dirt, check the pneumatic valve hole, and then wash the pneumatic valve hole. Between pneumatic valve seat and the ball even if only small particles of foreign matter may also damage the pneumatic valve seat sealing surface.
, the pneumatic valve is installed on the pipeline. Any end of the pneumatic valve can be installed at the upstream end. Pneumatic valve driven by the handle can be installed on the pipeline at any position. But with gear box or pneumatic actuator pneumatic ball valve should be installed upright, is installed in a horizontal pipe, and drive in the pipeline.
, pneumatic valve, flange and pipe flange gasket fitted according to the requirements of pipeline design.
, flange bolts need to be symmetrical, successive, evenly tighten.
, pneumatic pipeline connection ( Using pneumatic drive.
several times, drives the ball pneumatic valve opening and closing operation, should be no sluggish acerbity, confirmed that they work.
, according to the requirements of pipeline design and pneumatic ball valve between the flanges of the pipes in combination with surface sealing performance checks.
