The valve complies with PED 2014/68/EU directive, with special reference to Annex
III, Module A, concerning internal manufacturing checks as indicated in the Conformity
Assessment Procedures.
Valves with DN equal or smaller than DN25 are not included in compliance with Article 4, paragraph 3.
Valves designed for use with gases, liquefied gases, gases dissolved under pressure, vapours and also those liquids
whose vapour pressure at the maximum allowable temperature is greater than 0,5 bar above normal atmospheric
pressure (1 013 mbar) are included within the following limits:
- valves with DN between DN32 and DN100 (included) with group 1 fluids;
- valves with DN125 or bigger with group 2 fluids.
The end user must carry out noise assessment testing once the valve has been installed in the plant.
In the event of any doubt, please contact Bardiani Valvole S.p.A.
