Manual control valves Manual control valves are deemed to be simple slow-moving components, without any hot surfaces, and are not subject to ATEX Directive 94/9/EC. They can be integrated in devices and equipment conforming to the requirements of this directive without adversely affecting conformity. Nonetheless, parts of these components made of polymer can have an electrostatic charge and the user must take account of these charges.
