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]
