This document specifies the requirements for valves useable on transportable tanks with a minimum working pressure greater than 50 kPa for the transport of dangerous goods by road and rail for the following functions: Tanks for transport of liquid products: secondary closure of gravity discharge lines; primary closure on top of the tank (liquid, air, other connections); aeration valve on top of the tank; and other valves as defined in Annex F of EN 14564:2019. Tanks for gases: secondary closure of bottom discharge lines; secondary closure on top of the tank for poisonous gases: liquid phase and gas phase; and other valves as defined in Annex F of EN 14564:2019. This includes the following types of closures: valves (e.g. spindle operated valves, plug and ball valves, butterfly valves and gate valves); dry disconnect couplings. Primary closures of the gas phase at the foot of a tank for liquefied gas have to meet the requirements of foot valves according to EN 14433. NOTE The standard is also applicable to liquefied gases including LPG, however, for a dedicated LPG standard see EN 13175 [3]
