11 Normal operation

A properly designed pressure-regulating valve works automatically and does not need any form of auxiliary
energy.
To obtain optimum regulating accuracy, the desired operating pressure should be in the upper
part of the setting range of the pressure-regulating valve. This is described in detail in the "DM"
Section of the MANKENBERG catalogue under "Calculation of Pressure Regulators".

It is necessary to ensure that the materials selected for the parts of the fitting in contact with
media are suitable for the media in use. The manufacturer accepts no liability for any damage
due to corrosion by aggressive media on parts made of unsuitable materials.
danger of
Failure to observe this regulation may mean danger to life and limb and may cause
fatalities
damage to the pipeline system and to the fitting.
The fitting has functional parts that have to remain capable of moving easily. Make sure that
both the external springs and inner parts in contact with the medium cannot freeze nor become
blocked by dirt. Observe the maintenance intervals.
caution
Failure to observe this instruction may cause damage to the pipeline system and to the
fitting.
In some series a control line is laid between the pressure-regulating valve and the pipeline –
see section
danger
Damage to this control line may result in danger to life and limb and may impair the
function of the pressure-regulating valve or even lead to complete failure.
Pilot-controlled pressure-regulating valves are designed for the operating location in
accordance with the order. The restrictor assembly has 2 or 3 integrated restrictors with which
the operating response to pressure fluctuations can be influenced.
danger
Incorrect setting of the restrictors can cause damage in the system.
Pilot-controlled pressure-regulating valves are designed for the operating point in accordance
with the order. This operating point may occasionally be changed by the customer by means of
the adjusting screw. However, the setting of the adjusting screw must not be permanently
note
altered (e.g. by adding a valve actuator)
Failure to observe this instruction may cause damage to the pressure-regulating valve.
It is recommended that the fitting should be inspected to ensure that it is functioning correctly after each new
start-up.
