Intended use

The intended use of the Diaphragm valves MV3-VCR is to shut off and re-open a gas line.

Diaphragm valves of type MV3-VCR are suitable for flammable gases, non-flammable gases, oxygen as well as for ultra high purity gases from gas quality 6.0.

Depending on the equipment variant, the Diaphragm valves are suitable for the following types of gases:

• inert
• reactive (oxidizing, flammable/self-igniting, toxic/corrosive)

The permissible gas types and pressure ranges are each specified on the label (see "Identification / label").

The equipment versions of the Diaphragm valves without electrical components may be used in an explosion hazard zone as they do not have separate ignition sources (ignition hazard assessment according to DIN EN ISO 80079-36).

To be able to use the Diaphragm valves as intended, all persons working with it must comply with the specifications of the relevant user manual.

The area in which hazards can occur when used as intended is the area around the Diaphragm valves. The danger zone changes depending on the system status and use.
