The valve is maintenance free.
However, constant leakage can occur after blowing off due to abnormal operating conditions. This
leads to reduced performance and increases the compressed gas temperature. In this case check the
valve and replace as necessary.

6.7 Decommissioning

into the environment) and dispose of it according to the regulations. When the compressor is depres-
surised, undo the fastening screws of the shut-off valves. Remove the compressor using an appropri-
ate hoist. Dispose of the oil inside in accordance with the valid national regulations.
