This document specifies the requirements for valves useable on 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 bottom discharge lines; – primary closure on top of the tank (liquid, air, other connections); – aeration valve on top of the tank; – and other valves as specified in Annex F of EN 14564:2019 according to the scope of this document. 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 specified 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 are covered by the requirements of foot valves in EN 14433. NOTE The standard is also applicable to liquefied gases including LPG, however, for a dedicated LPG standard see EN 13175 [3]
