Pilot-controlled pressure regulators DM

1 Introduction

This manual is intended to assist users of a MANKENBERG pressure-reducing, backpressure regulator,
vacuum control valve, differential pressure control valve or flow control valve during installation, operation and
maintenance. Read the manual thoroughly before installing or putting this valve into service.

2 Intended use

A MANKENBERG DM pressure-reducing valve is a device that is intended exclusively for automatically
regulating the outlet pressure of the medium (without any additional electrical/pneumatic energy) after it has
been installed in a pipeline system. The force of the outlet pressure acts on a control mechanism (diaphragm,
piston or bellows) and is in balance with the preload of a spring that has to be adjusted by the user to the
required value within the setting range of the valve.
A MANKENBERG UV backpressure regulator is a device that is intended exclusively for automatically
regulating the inlet pressure of the medium (without any additional electrical/pneumatic energy) after it has been
installed in a pipeline system. The force of the inlet pressure acts on a control mechanism (diaphragm, piston or
bellows) and is in balance with the preload of a spring that has to be adjusted by the user to the required value
within the setting range of the valve.
A MANKENBERG VV vacuum control valve is a modification of the pressure-reducing or backpressure
regulator, built to regulate pressures in vacuo. It only regulates the differential pressure to the atmosphere.
A MANKENBERG DV differential pressure control valve is a modification of the pressure reducing or back
pressure regulator, built to regulate differential pressures.
A MANKENBERG MR flow control valve is a modification of the pressure – reducing or backpressure
regulator, built to regulate flow rates.
A pressure-reducing valve / backpressure regulator / differential pressure control valve / flow
control valve / vacuum control valve is not a safety valve. A suitable valve must be present in
the system to limit any excess pressure.
danger
Pressure-regulating valves are generally supplied with a slackened spring and have to be
adjusted to the required pressure after being installed. The required pressure measuring
devices must be installed in an adequate distance in front of and behind the fitting.They are

MANKENBERG planning documents are available to give users precise assistance in selecting and designing
the appropriate fitting, e.g.:
In the section < DM: Regulating valves for pressure>
<Design of pressure-regulating valves>
<Know-how on pressure-reducing valves / backpressure regulators>
<Type sheet DM... / UV... / VV... / DV... / MR...> with technical data and tables of the setting ranges and the
dimensions.>
