H L Model x.xxxxx x.xxxxx x.xxxxx Contact face acc. to DIN EN /B Note to ressure Equipment Directive (ED): The valves of this series, including the connection size DN 25 (G1), are according to rt. 4 3 of the ressure Equipment Directive (ED) 2014/68/EU (97/23/EG). This means interpretation and production are in accordance to engineers practice wellknown in the member countries. The CE-sign at the valve refers not to the ED. Thus the declaration of conformity is not longer applicable for this directive. Note to Electromagnetic Compatibility Guideline (EMC): The valves shall be provided with an electrical circuit which ensures the limits of the harmonised standards EN and EN are observed, and hence the requirements of the Electromagnetic Compatibility Guideline 2014/30/EU (2004/108/EG) satisfield. For valves > DN 25 (G1) rt. 3 (1) No.1.4 applies: The basic requirements of the Enclosure I of the ED must be fulfilled. The CE-sign at the valve includes the ED. certificate of conformity of this directive will be available on request. en
