:
Directive 2014/68/UE : Equipments under pressure PED
(Pressure Equipment Directive)
Applies to the design, manufacturing and the assessment of the conformity of pressure equipment, the maximum allowable pressure of
which is 0.5 bar.
Pressure equipment for water supply, distribution, and disposal of water is excluded.
Depending on the type of pressure equipment, maximum allowable temperature (PS), DN, physical nature of the fluid (liquid, gas
or vapour) and the degree of danger of the fluid (group1/2)*, the directive classifies this same equipment into different categories
(article 3.3, I, II, III, IV), required for the assessment of conformity with CE marking.
The equipment defined in article 3.3 of the directive must not bear the CE marking.
(*) Group 1 : hazardous fluids (directive 67/548/EEC) / explosive / highly flammable /easily flammable / flammable / very toxic / toxic /
combustion agents.
Group 2 : all other fluids
Important notice : the indicated pressure for the different categories of fluids (L1/L2/G1/G2) is under no condition a guarantee of use.
Therefore, it is essential to validate the use of products under given operating conditions. Socla is not responsible for alteration of the pro
-
ducts to working conditions not previously specified by the customer.
In order to facilitate your choice regarding these new regulatory requirements, Socla has put the necessary information
concerning products with CE marking, specification sheets and product identification plates at your disposal in the price list (+ see additional
explanations on the detachable slip).
In addition, the operating instructions are available on our web site www.socla.com or by simple request from our sales department.
Machinery Directive 2006/42/CE : Machinery Directive
In its Appendix I it sets a certain number of Essential Health and Safety Requirements which must be met. It applies to motorised butterfly
valves, (with electric, pneumatic or hydraulic actuators). According to this Directive, these sets are “Partly Completed Machineries” designed
for being integrated into a machine.
“Partly Completed Machinery” means an assembly which is almost machinery but which cannot in itself perform a specific application. A drive
system is partly completed machinery. Partly completed machinery is only intended to be incorporated into or assembled with other machi-
nery or other partly completed machinery or equipment, thereby forming machinery to which this Directive applies.
