DEUTSCHE NORMUDC 621.646.616-034 October 1989 DIN Metal ball valves 3357 Part 1 General requirements and methods of test Supersedes August 1982 edition. Kugelhähne; allgemeine Angaben für Kugelhähne aus metallischen Werkstoffen 1 Field of application This standard provides general information regarding the presentation of standards dealing with general purpose metal ball valves. It specifies details to be included in the standard designation,and also requirements and methods of test for ball valves with regard to dimensions,valve pattern, trim, body materials and marking. 2 Nominal sizes and pressure ratings The nominal sizes shall be selected from DIN 2402 and the pressure ratings, from DIN 2401 Part 1. 3 Designation The standard designation for ball valves as specified in the DIN 3357 series of standards shall take the following form: Ball valve DIN 3357 - X XXXX PN XXX - - XXX XXX - Term DIN number Hyphen Letter symbol denoting face-to-face or centre-to-face dlmension if different sizes are assigned to one pressure rating Nominal size Symbol denoting 'pressure rating' Nominal pressure Hyphen Code number (number of relevant Part of DIN 3357) Type symbol (the type symbol covers valve pattern, material and trim) 1 4 Dimensions 4.1 Face-to-face and centre-to-face dimensions The face-to-face or centre-to-face dimension shall be selected from DIN 3202 Part 1(flanged end ball valves),DIN 3202 Part 2 (weld end ball valves), DIN 3202 Part 3 (wafer type ball valves), DIN 3202 Part 4 (threaded end ball valves), or from DIN 3202 Part 5 (ball valves with compression ends). 4.2 Space requirement In DIN 3357 Parts 2 to 7,the space requirement dimensions are specified as the maximum dimensions of the enveloping body enclosing a ball valve with handwheel. In the case of ball valves which are not capable of being operated by a handwhee1,the height required is the distance between bottom end of valve body and top end of stem.
