About this product
1 About this product
The relief valve protects pumps from impermissible overpressure caused by operational
faults or blockages.
The universal relief valve type DHV-UR is a continuously adjustable plunger diaphragm
valve with an internal flow. In the event of impermissible overpressure, the internal
plunger diaphragm opens the second outlet line, the relief outlet. The relief valve can be
installed at any location in the pipework system. There are only very low pressure losses
due to the virtually free pipe cross-section.
Fig. 1: Scope of delivery: relief valve with seals for the connector.
A manometer can also be installed on the “M” version of the relief valve DHV-UR.
The relief valve is also available as an FDA-approved version.

2.2 User qualification
WARNING!
Danger of injury with inadequately qualified personnel
The operator of the system / equipment is responsible for ensuring that the qualifi‐
cations are fulfilled.
If inadequately qualified personnel work on the unit or loiter in the hazard zone of
the unit, this could result in dangers that could cause serious injuries and material
damage.
– All work on the unit should therefore only be conducted by qualified per‐
sonnel.
– Unqualified personnel should be kept away from the hazard zone.
The pertinent accident prevention regulations, as well as all other generally
acknowledged safety regulations, must be adhered to.
Training Definition
Instructed personnel An instructed person is deemed to be a person who has been
instructed and, if required, trained in the tasks assigned to him
and possible dangers that could result from improper behav‐
iour, as well as having been instructed in the required protective
equipment and protective measures.
Trained user A trained user is a person who fulfils the requirements made of
an instructed person and who has also received additional
training specific to the system from the manufacturer or another
authorised distribution partner.
Trained, qualified
personnel
A trained, qualified employee is deemed to be a person who is
able to assess the tasks assigned to him and recognize pos‐
sible hazards based on his training, knowledge and experience,
as well as knowledge of pertinent regulations. A trained, quali‐
fied employee must be able to perform the tasks assigned to
him independently with the assistance of drawing documenta‐
tion and parts lists. The assessment of a person's technical
training can also be based on several years of work in the rele‐
vant field.
17
Safety chapter
Training Definition
Electrical technician An electrical technician is able to complete work on electrical
systems and recognise and avoid possible dangers independ‐
ently based on his technical training and experience as well as
knowledge of pertinent standards and regulations. An electrical
technician must be able to perform the tasks assigned to him
independently with the assistance of drawing documentation,
parts lists, terminal and circuit diagrams. The electrical techni‐
cian must be specifically trained for the working environment in
which the electrical technician is employed and be conversant
with the relevant standards and regulations.
Service The Service department refers to service technicians, who have
received proven training and have been authorised by the man‐
ufacturer to work on the system.

2.3 General safety information
WARNING!
Danger from hazardous sub‐
stances!
Possible consequence: Fatal or
very serious injuries.
Please ensure when handling haz‐
ardous substances that you have
read the latest safety data sheets
provided by the manufacture of the
hazardous substance. The actions
required are described in the
safety data sheet. Check the safety
data sheet regularly and replace, if
necessary, as the hazard potential
of a substance can be re-evaluated
at any time based on new findings.
The system operator is responsible
for ensuring that these safety data
sheets are available and that they
are kept up to date, as well as for
producing an associated hazard
assessment for the workstations
affected.
Safety chapter
WARNING!
Feed chemical can escape from
the DHV.
In the event of a diaphragm rupture
or insufficiently tightened housing
screws, feed chemical can escape
from between the housing parts or
through the adjusting screw.
Feed chemical can leak out from
insufficiently tightened sealing
stoppers or manometers.
– Produce an appropriate action
plan, based on these operating
instructions and the material
safety data sheet for your feed
chemical, to be used in the
event of uncontrolled leakage
of feed chemical.
CAUTION!
FDA valves only: problems with
hygiene are possible
The valves and the seals supplied
can become dirty from the pack‐
aging and shipment.
– Thoroughly clean the seals
supplied before use and flush
through the relief valve.
19
Safety chapter
n Only the flow volume of the con‐
nected pump can be re-directed with
the DHV-UR.
n Take appropriate precautions on the
system when using as a relief valve
with sticky media, for example with
styrene: rinse the relief valve if it has
possibly reacted.
n Prior to installation, remove water
from the relief valve if it is to be used
together with media that may not
come into contact with water.
n The DHV-UR relief valve is not a
safety valve according to DIN EN ISO
4126-1.
n The DHV-UR relief valve is not
intended for use as a completely leaktight shut-off device.
n The DHV-UR relief valve is not
intended for use with gaseous media
or solids.
n Do not use the DHV-UR relief valve
with abrasive or crystallising media.
n Do not allow the DHV-UR relief valve
to come into contact with liquids,
which corrode the material of the
relief valve. This also applies to
cleaning agents and fats. Refer to the
ProMinent Resistance List in the
product catalogue or at www.promi‐
nent.com in this respect.
n Do not operate the relief valve outside
the ambient and operating conditions
specified in these operating instruc‐
tions.
n Only allow trained and authorised per‐
sonnel to operate the relief valve.
n You have a duty to observe the infor‐
mation contained in the operating
instructions during the different
phases of the system's service life.

Safety chapter
2.3.1 Information in the event of an emergency
In the event that feed chemical escapes from the relief valve, depressurise the hydraulic
surroundings of the relief valve and refer to the material safety data sheet for the feed
chemical.
If you have to depressurise the relief valve in an emergency:
Fig. 4: Relieving pressure
Remove the cap (11). Loosen the locking nut (14) and unscrew the adjusting
screw (13).
The pressure now drops through the relief outlet.

Safety chapter
2.4 Intended use
n The relief valve DHV-UR is only
intended for use with liquids.
n When used correctly as a relief valve,
the relief valve DHV-UR limits the
operating pressure of the pumps and
protects pumps from overpressure
caused by operational faults or block‐
ages.
n The properties of the relief valve
DHV-UR can only be guaranteed
when used in conjunction with ProMi‐
nent pumps.
n All other uses or modifications are
prohibited.

CAUTION!
As supplied, the relief valve is set to 0 bar.
As the relief valve has not yet been set, there is a risk of hazardous situations
occurring when starting up the system or opening the shut-off devices, as the
relief valve is not yet capable of releasing impermissible overpressure.
