Explosion hazard due to modifications to the valve!
In the event of changes to the surface protection of the valve, the following points
must be observed:

substances. This leads to a loss of the explosion protection.

EN 80079-36, section 6.7; otherwise, explosion protection can no longer
be ensured.

▶ It is imperative to provide for absolute cleanliness. The valve must be protected
from dirt during installation. Contamination of the hydraulic fluid may
considerably reduce the life cycle of the valve.
