Cleaning the Valve
CAUTION
Cleaning agents spraying out due to excess pressure in the container to be
cleaned
If the container to be cleaned is under excess pressure, the pressure is released into the
atmosphere during lifting. If this happens during cleaning, when cleaning solution is
continuously sprayed into the valve housing, the air flowing out carries the cleaning solu-
tion along. This liquid can spray out of the collecting pan for the vacuum pan. Depending
on the level of the excess pressure, a considerable amount of cleaning solution can
emerge. These effects are physical and cannot be avoided.

Use the lifting function only when the container is not under pressure.

Lift the pressure relief valve disk before lifting the vacuum valve disk, in order to
reduce spraying if a residual overpressure exists.

Use the lifting function only when the collecting pan for the vacuum valve is empty.
IMPORTANT NOTE
Valve disk, housing seat and valve seat are precision parts.
Damage to these parts can result in malfunctions.

Handle the valve with care!
