Safety instructions and measures
Referenced standards and regulations
The control valves comply with the requirements of the European Pressure Equipment Direc -
tive 2014/68/EU. Valves with a CE marking have a declaration of conformity which in -
cludes information about the applied conformity assessment procedure. This declaration of
conformity is included in the Appendix of these instructions (see section 10.2).
According to the ignition risk assessment performed in accordance with EN 13463-1:2009,
section 5.2, the non-electrical control valves do not have their own potential ignition source
even in the rare incident of an operating fault. As a result, they do not fall within the scope of
Directive 2014/34/EU.
Î
For connection to the equipotential bonding system, observe the requirements specified in
section 6.4 of EN 60079-14 (VDE 0165 Part 1).
