Considered separately, a valve is a non-electrical device that does not have a potential ignition source of its own. However, when installed and working within an operating environment, valves are capable of becoming electrostatically charged and causing hot surfaces. Thus, ultimately, they can indeed be considered a potential source of ignition. For this reason, valves come under the scope of the ATEX Directive 2014/34/ EU. Issue: 2019/2020
