Selection and qualification

Qualified users
Qualified users are specialized personnel with the required knowledge and ex-
perience who have been trained to carry out such work. The specialized per-
sonnel must be able to recognize and avert the dangers which they are ex-
posed to when working with and on the valves.
In particular, these specialized personnel must be authorized to operate,
earth/ground and mark hydraulic and electrical devices, systems and power
circuits in accordance with the standards of safety engineering. Project plan-
ners must be fully conversant with automation safety concepts.
Warranty and liability claims for personal injury or damage to property are
among others excluded if such injury or damage is caused when the valves are
worked on or handled by non-qualified personnel.

In the interests of avoiding damage to the valves or acces-
sories, structural modifications, on account of the com-
plexity of the internal components of the valves or acces-
sories, may only be carried out by us or one of our autho-
rized service centers.
