11. TROUBLESHOOTING
POTENTIAL EFFECT OF FAILURE
Loss or reduction of the supplied
torque
Leaks from the stem upper or lower
seals
Leakage form cylinder caps
Leakage from the ports after
manoeuvre
Insufficient valve rotation
12. DISPOSAL OF PRODUCTS AT THE END OF THEIR LIFE CYCLE
The ACTUATECH products are designed so that when they are at the end of their life cycle they can be completely disassembled,
separating the different materials for the proper disposal and/or recovery. All materials have been selected in order to ensure minimal
environmental impact, health and safety of personnel during their installation and maintenance, provided that, during use, they are
not contaminated by hazardous substances.
The personnel in charge of the product disposal/recovery, must be qualified and equipped with appropriate personal protective equi-
pment (PPE), according to the product size and the type of service for which the device was intended. The management of waste
generated during the installation, maintenance or due to the product disposal, is governed by the rules in force in the country where
the product is installed, in any case, the following are general guidelines:
- The metal components (aluminium/steel) can be restored as raw material;
- Seals/sealing elements (NBR, FPM, FVMQ...), as contaminated by fluids from other materials and lubrication, must be disposed of.
- The packaging materials that come with the product, should be transferred to the differentiated collection system available in the
country.
13. DECLARATION OF CONFORMITY
The ACTUATECH S.p.A. actuators have been designed, manufactured and tested to meet the requirements of the following Europe-
an standards and are marked, where provided, with the relative CE conformity marking:
- 2006/42/EC Directive "Machinery";
- 2014/34/EU Directive "Equipment and protective systems intended for use in potentially explosive atmospheres" (ATEX).
