This European standard specifies the general requirements for the construction, performance
and safety of ball valves and closed bottom taper plug valves. It also details the test methods and
marking requirements.
It applies to metallic valves for domestic and commercial not directly buried installations inside or
outside of buildings, using gases of the first, second and third family (specified in EN 437) and working
up to 0,2 × 105 Pa, 0,5 × 105 Pa and 5 × 105 Pa.
Valve nominal sizes (DN) covered by this European standard are as follows:
6, 8, 10, 12, 15, 20, 25, 32, 40, 50.
