Linear and diameter dimensions are in mm; weights are in kg. Pressure bands are in MPa (1 MPa = 10 bar). Height and length datums follow the drawing. Thread designations and ISO mounting codes are not linear dimensions. PN320 supplied socket-weld arrangement, DN15-DN25. Two DN20 body variants are listed. DN10 is not tabulated. Source body material is S30408; the catalogue CF8 construction needs its own confirmed drawing. Use the approved order drawing for installation and fabrication.
