4Competence in Functional SafetyFunctional safety of globe valves, rotary plug valves, ball valves and butterfly valves1 ScopeValves and the associated actuators are used to isolate pipelines in safety-instrumented systems. Alternatively, they canalso be used for pressure relief, i.e. by completely opening valves.2 Validity of this manualThis manual applies to control valves manufactured by the following companies within SAMSON: SAMSON AG LEUSCH GmbH Industriearmaturen PFEIFFER Chemie-Armaturenbau GmbH VETEC Ventiltechnik GmbHRefer to the manufacturer‘s declarations in Appendix 1 of this manual for the valve models concerned.The individual versions of the valves can be identified by their nameplates10 EB 8310-7 ENMarkings on the device2 Markings on the device2.1 Actuator nameplateThe nameplate is stuck on the diaphragm casing.
