For example, 32 of the ball valve, series one, body length is 165, series two length is 147, as if the two series what is the difference?
First of all, for the same caliber, the body length is changed according to the pressure gradeDN32 ball valve, in its PN16, PN40, PN100 and other pressure levels, the surface spacing is differentFor the same specifications and pressure levelsThe general standard gives 2 or 3 series for users and manufacturers to choose fromSuch as GB GB/T 12221 ball valve requirementsDN32 PN16 ball valve spacing of 3, 140165180, of which 165 is the preferred optionThey all meet the standard, so you can choose any one as the distance between them,If there is no indication of which series to use, the general use of priority options
According to the working conditions of the pipeline, choose the proper length of the valve body and match the pipe
A long series; a short series
