PLASTIC VALVES ACCORDING TO ATEX


NEW GUIDELINES ACCORDING TO ATEX 2014/34 / EU




ATEX DIRECTIVE 94 / 9EG



Since 01.07.2003, valves intended for use in explosion-hazard zones must be approved in accordance with Directive 94/9 / EC.
From 20.04.2016 the guideline 2014/34 / EU will apply.

Link:
DIRECTIVE 2014/34 / EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 26 February 2014

This so-called ATEX Directive aligns the various requirements within the EU so that a uniform level of safety can be achieved.
 


VALVES MADE OF ELECTRICALLY CONDUCTIVE POLYPROPYLENE (PP-EL)




MATERIAL DESCRIPTION



For special applications, the manufacturer SAFI has developed a new range of conductive PP fittings with a graphite content.
The graphite accessory allows these "HIGH-PERFORMANCE" valves to achieve electrical resistance values ​​that are well below the prescribed limits of the current ATEX directive.
A high quality plastic that conducts electricity. Thus, the emergence of static charge inside the valve is already avoided in advance.



ATEX RANGE


Our conductive ball valves have already been available and in use for several years as hand-operated valves in sizes DN 15 to DN 100. Optionally we deliver the fittings with EPDM, FKM and FEP / FFKM seals. In addition, they are available with ATEX-compliant pneumatic or electric drives including accessories.



  As a further product group, we are now offering three different angular seat fittings in the product range. From April 2016, SAFI manual shut-off valves, check valves and strainers in sizes DN 15 to DN 50 made of conductive PP are also available.




CERTIFICATE OF COMPLIANCE



SAFI certifies that the ball valves and angle seat fittings we supply are made of conductive polypropylene. The ball valves, with a specific resistance of <1,000,000 ohms, as well as the oblique seat fittings, with a specific resistance of <10,000 ohms, are classified as electrically dissipative (non-chargeable) and therefore comply with the ATEX directives.
The conformity of our valves is certified by us in cooperation with external testing institutes.


For further information we are always available. We will gladly send you the requested data sheets or certificates. Of course, we also advise you on site about the possible applications of our conductive fittings and make you a corresponding offer for your application.
Please send us an inquiry.
