Ball Valve Design Calculations . Nominal pressure=350 bar design pressure or test pressure = nominal pressure x factor of safety p = 350 x1.4 = 490 bar p= 49 n/mm2 as per din standard the new pressure of ball need to change the specific bore size on ball per standard therefore, dn = 30mm.which specifies the bore size of a valve and also the valve size.
