Page 4: General Safety Instructions
2014/68/EU. Valves with a CE marking have a declaration of conformity which includes information about the applied conformity assessment procedure. The declaration of conformity can be viewed and downloaded from u http://www.samson.de. − To ensure appropriate use, only use the valve in applications where the operating pres- sure and temperatures do not exceed the specifications used for sizing the valve at the or- dering stage. - Page 5 General safety instructions Note: − For installation and maintenance, make sure the relevant section of the pipeline is depres- surized and, depending on the process medium, drained as well. Depending on the field of application, allow the valve to cool down or heat up to reach ambient temperature be- fore starting any work on it.
