Operation
7.2
Working in manual mode
Valves with actuators with a handwheel can
be manually closed or opened in case of
supply air failure.
7.3 Lubricator for the packing
chamber
In some applications, a lubricator for the
packing chamber is required. This lubricator
is fitted with a check valve to prevent return
flow into the process medium. In some
valves, a shut-off valve is additionally in-
stalled for better protection.
Î
The lubricator must always be filled with
lubricant and be attached firmly to the
valve (but not tightened too tight).
Î
Turn the lubricator one or two turns every
two weeks to achieve the required seal-
ing performance.
