Operating Instructions Flow Limiters SMBM-X and SMBM-V EEX Created on: 05-03-2021 Document no.: 951-180-090-EN Version: Read these instructions before installation or start-up of the product and keep them readily available for later consultation.
EU Declaration of Conformity in accordance with Directive 2014/34/EU, Annex X We hereby declare, under our sole responsibility, that the device conforms Designation: Flow limiter Type: SMBM-…EEX Item number: 5788-… / 6788-… Year of manufacture: See type plate to all relevant harmonization legislation of the European Union at the time of placing on the market. The technical documentation pursuant to: ATEX Directive 2014/34/EU Annex VIII No.
Explosion protection marking in accordance with Directive 2014/34/EU SMBM flow limiters without electrical attachments The ignition hazard analysis conducted in accordance with EN 80079-36 / -37 found that SKF flow limiters of the series SMBM without electrical attachments do not constitute own potential sources of ignition. They consequently do not fall under the scope of Directive 2014/34/EU and thus do not bear explosion protection marking.
Warranty Masthead The instructions contain no statements regarding the warranty or liability for defects. That information can be found in our Manufacturer General Terms of Payment and Delivery.
