If required, Mankenberg will assist in selecting a suitable type with closed bonnet.
If a pressure-regulating valve has to be dismantled:
The following must be observed at all costs: First release the tension fully on the spring by

follow the notes in section
Then either seal off the two shut-off valves installed upstream and downstream of the valve in
accordance with the Mankenberg installation recommendation and vent the pressure-
regulating valve, or remove the pressure from the section of the system and then remove the
valve from the pipeline.
If a valve is removed from a system with a toxic medium and is taken out of the plant:
it must be properly decontaminated before repair.
caution
Possible malfunction due to external influences
External influences, e.g. pressure on the vent hole, can cause control deviations or damage
internal parts.
note
When cleaning the outer surface, do not hold the high-pressure steam cleaner or compressed
air blow-off gun near the vent hole.
Malfunction due to clogging of the vent hole
External influences, e.g. covering, clogging or sticking of the vent hole, may interfere the
control behavior of the valve. The valve no longer controls reliably.
note
The vent hole must be kept free!

6 Transport and storage

A valve must be handled, transported and stored with care:
» The valve must be transported and stored in its protective packaging until it is installed.
The valve has moving internal parts.
Even packed valves should be transported smoothly without any shocks.
caution
In the case of a valve that can no longer be transported by hand, the lifting gear must be
attached to a suitable position on the housing (branches).
Under no circumstances may the lifting gear be affixed to any attachments (adjusting
caution
screw, handwheel or accessories).
