Tanks for the transport of dangerous goods - Tank equipment for the transport of liquid chemicals and liquefied gases - Product discharge and air inlet valves
This European Standard specifies the requirements for product discharge and air inlet valves for use on transportable tanks with a minimum working pressure greater than 50 kPa for the transport of dangerous goods by road and rail.
NOTE 1 The term 'valve' includes ball valves as well as butterfly valves and similar closure devices.
It is applicable to metallic equipment for use on tanks with gravity and/or pressure filling and discharge for liquid chemicals and liquefied gases. It includes carbon dioxide while excluding refrigerated liquefied gases.
NOTE 2 The standard is also applicable to liquefied gases including LPG, however, for a dedicated LPG standard see EN 13175 [3].

— the technical annexes of the ADR.
NOTE These regulations take precedence over any clause of this document. It is emphasized that RID/ADR are
being revised regularly at intervals of two years which may lead to temporary non-compliances with the clauses of
this document.Compared with EN 14432:2014 the following significant changes apply:

1 Scope
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]2 Normative references
