2 SAFETY INFORMATION
The AWG B pressure valves described here are in line with the state of
the art as well as the recognised safety regulations. The safety and
health protection requirements have been met. Nevertheless, their use
may give rise to hazards for the user or third parties or cause damage
to the device itself or other material assets.
2.1 General safety instructions
The device may only be operated in accordance with these instruc-
tions and in perfect condition.
The operators must have received the necessary training to be able
to handle the device properly.
Unauthorised modifications or the installation of additional compo-
nents not approved by the manufacturer endanger the proper func-
tioning of the device.
– Modifications to the device are prohibited
– Only use accessories approved by the manufacturer
The operator is responsible for safety in the vicinity of the device, in
particular for compliance with the general safety regulations. This in-
cludes ensuring, before using the device, that all protective devices
are fully in place and functional.
2.2 Safety during operation
Observe all safety rules and protective measures applicable for use
at the place of use.
Make sure the device does not get damaged during transport, instal-
lation, commissioning, operation or maintenance.
The safety regulations laid down in the country-specific service reg-
ulations for fire-fighters (for example in Germany the Feuerwehr-
dienstvorschrift FwDV) or the corresponding internal company regu-
lations must be observed.

2.3 Qualifications of the operators
Persons handling or using the pressure valve must be technically quali-
fied and trained. They must be aware of all risks involved in handling the
device.
The pressure valve may only be used by persons who have been trained
and instructed in the operation of the device in accordance with the
country-specific fire service regulation (in Germany: FwDV) or corre-
sponding internal company regulations.
Different qualifications are required for personnel performing the differ-
ent types of activity.
Instructed personnel:
Transport / use / cleaning as well as "Basic" functional testing
Technical personnel:
Maintenance as well as "Standard" and "Advanced" functional testing
2.4 Personal protective equipment

lation (e.g. in Germany: FwDV) or with internal company regulations, in
action.
3 DESCRIPTION
3.1 Function
B pressure valves according to DIN 14381:2017-04 serve as shut-off
devices for the pressure outlets of centrifugal fire pumps.
The pressure valve has a non-return function that closes automatically
during the venting process (priming). In the event of a brief interruption
of pump operation, this eliminates the need for a new venting process.
The outlet pressure of the centrifugal fire pump opens the valve against
the spring force.
To open the non-return valve manually, pull the knob of the spindle lock
and turn the hand wheel further out counter-clockwise. The valve disc is
thereby mechanically lifted from its seat, the non-return valve is overrid-
den. This function can be used, for example, to relieve pressure built up
in the delivery lines via the centrifugal fire pump.

AWG I Operating manual I Valves I B pressure valves DESCRIPTION
8 / 21 M1125B10 I Rev. 01-03/22
In the "Servo" version, the valve disc is also hydraulically balanced. This
reduces the torque required to close the valve against the pump pres-
sure. The closing torques of the standard valves are significantly higher
and comply with the design specifications of the product standard.
The pressure valve is used to slowly open and close a pressure outlet,
thus avoiding hazards and damage due to pressure surges.
For water delivery, the pressure valve should be opened as fully as pos-
sible. It is not possible to regulate the flow rate by intermediate positions
of the valve, as the valve can open automatically during operation due
to external influences such as flow, vehicle and turbulence vibrations.
3.2 Intended use
Shutting off the pressure outlets of fire pumps
Opening and closing the pressure outlet
Only use the device in technically sound condition and in accordance
with the intended purpose and with safety and potential dangers in mind.
3.3 Foreseeable misuse
Use to control the flow rate (no intermediate positions allowed)
Use beyond the country-specific fire brigade regulations (in Ger-
many: FwDV)
Conversion or modification
Operation in technically unsound condition
Operation outside the approved characteristic values
Fitting of spare parts that are not approved or not suitable for the
operating conditions
