1) Consecutively assigned code number for valves from a production order.
2)
Consecutively assigned number. This number is identical with the valve no. in the related
certificate regarding the setting of safety valves (setting certificate) and thus allows for the
unambiguous assignment of the valve to this setting certificate. If one production order comprises
several identical safety valves, the same number may be assigned to all valves from this production
order. The related setting certificate will then apply to all identical valves of this production order
and to the customer's or production order number specified in the setting certificate, the total
number x of the valves will be added in the form /1 – x.
3)
Alternatively, the CE mark may also be embossed at the valve body.
