3.1. scope of application
These operating instructions are only valid for the following valves:
Disk type non-return valves
Type P740 / P741 / P745 / P750 / P760
Sizes DN 010 – 150
OD 0.50” – 6.00”
ISO 008 – 125
3.2. Use, structure and method of working
The disk type non-return valves stop the return flow of fluid media against the desired direction of flow.
These spring-loaded disk type non-return valves are characterized by the fact that a flow path can be closed in one
particular direction by a closing body fitted with an elastomer seal by way of a spring, and opened in the other
direction thanks to the pressure of the flowing liquid.
When in the closed position, the closing body is pressed into the seal seat either by way of spring tension or by
way of the superposition of the spring tension with a parallel compressive force.
If a level pressure that is able to overcome the aforementioned restoring forces builds up in the forward direc-
tion, the closing body is then lifted from the seal seat and the flow is released.
The disk type non-return valves each have a valve seat and a closing body
The valve seats are each axially sealed.
It is preferable to install disk type non-return valves downstream of the pumps in piping systems.
If they are installed there, the valves stop media from being able to flow back into a system area with a lower
pressure level (e.g. in a pre-separation tank) in the event there is a pump fault in a system area with a higher
pressure level (e.g. a pressure tank).
3.3. Storage
Store the valve in a dry place protected against external influences.
Do not expose to direct sunlight
Prior to handling (disassembly of the valve body), temporarily store the valves in a dry place at an ambient tem-
perature of ≥ 5° C for at least 24 hours.
3.4. Service Life
The foreseeable service life of disk type non-return valves is 15 years.
3.5. ATEX Use
The disk type non-return valves comply with the requirements of Directive 2014/34/EU of the European Parliament
and the Council and are suitable for use in potentially explosive atmospheres.
The valves must not be operated outdoors, if its service location there is classified as area with risk of explosion
pursuant to Directive 2014/34/EU of the European Parliament and of the Council.
Usage of the disk type non-return valves ”underground” is not permitted.

3.8.1. Limiting devices
In order to prevent the operating thresholds, such as pressures and temperatures, described in “Permissible operating
media, pressures and temperatures” either being exceeded or not reached, the system, in which the disk type non-
return valves are integrated, must be equipped with the following limiting devices:
Control devices:
Suitable, manually or automatically operable control devices to maintain the operating parameters within the per-
missible threshold values.
Monitoring devices:
Suitable monitoring devices, which enable appropriate manual or automatic intervention, trigger corrective
measures and/or shutting down or locking, in order to maintain the operating parameters within the permissible
threshold values.
Safety devices:
Suitable safety devices such as safety valves or burst disk safeguards, which ensure, as the last hazard prevention
measure, that the permissible operating pressures described in "Permissible operating media, pressures and tem-
peratures” are not exceeded.
3.8.2. Instructions for all disk type non-return valves
DANGER
If liquids, emulsions or fluids in the valve are above their evaporation temperature at
atmospheric pressure, sudden evaporation of the entire contents of the pipeline into the
operating chamber and consequently a risk of injury for persons in the operating room may
occur when the valve is switched on or when leakage occurs due to seal wear.
The disk type non-return valve operator must ensure that hot media do not exceed the
ignition temperature in the pipeline system.
Information/notice
When using ready-made cleaning agents or other aggressive media, make sure that these
are suitable for the stainless steel and sealing material used and that they do not cause any
damages to these materials.
In case of doubt, please consult the valve manufacturer.
3.8.3. Hygiene instructions for all disk type non-return valves in the foodstuffs industry
The operator of the disk type non-return valves must ensure that the valves are used exclusively in accordance with
their intended use.
This particularly applies to the exclusive use of admissible media, to the exclusion of inadmissible media and compliance
with the permissible concentrations and temperatures of cleaning agents and disinfectants.
It also applies in particular to compliance with the measures as described in a maintenance plan, which ensure that the
required hygiene status of the fittings is maintained within fixed intervals. These measures include regular cleaning-in-
place (short: “CIP”) of the valve interior. In some cases, this includes regular “Sanitization-in-place" disinfection (short:
“SIP“) of the valve interior.

required for the commissioning of the valves is available to the operating personnel.
The operator of the disk type non-return valves must ensure that the required safety and limiting systems of the
fittings as described in the “limiting systems” chapter are continually functional and that they cannot be switched
off whilst operating or changed with respect to their intended use.
Commissioning of the disk type non-return valves includes
a wet test, including testing of the valve opening behavior
a pressure and sealing test
thorough cleaning of the valves, if they are earmarked for processing foodstuffs.
Wet test, opening behavior, pressure and sealing test:
Run cold water through the valves.
Opening of the disk type non-return valves must be possible in a secure fashion with a primary pressure of
0.1 bar.
Pressurize valves.
To do this, seal the media supply line filled entirely with cold water located downstream of the disk type non-
return valves with a suitable isolation valve and apply the test pressure upstream of the disk type non-return
valves.
Test sealing of fittings by visual check.
In case valves are not watertight, de-pressurize, empty and disassemble them.
Check the appearance and assembly status of seals; replace seals if necessary.
Conduct pressure and sealing test again.
Repeat the process as many times as required until there are no further leakages.
Basic cleaning:
If the disk type non-return valves come in contact with foodstuffs, the operator of the valves should clean the
fittings thoroughly before food is processed in it.
See the chapter “Cleaning, Disinfection” for this purpose.

7. Maintenance of disk type non-return valves
DANGER
The operator of the fittings must ensure that all people carrying out activities on the
fittings are suitably qualified and also able to recognize whether the closing bodies of
these fittings are located in their immobile final locations within the fittings.
In addition, the operator of the fittings must ensure that these people are instructed not
to reach into the media connections on the fittings if this is not already the case.
During servicing, maintenance, and disassembly of the disk type non-return valves, it
must be ensured that power-driven switching operations can only be initiated by people
working directly on the valves.
The operator of the disk type non-return valves must ensure that all people who carry
out this activity are suitably qualified and are also able to recognize whether power-
driven switching operations on the fittings, apart from by themselves, can be actuated
by someone else.
7.1. Inspection of the disk type non-return valve
Disk type non-return valves must be checked at regular intervals and maintained as required.
7.2. Maintenance, troubleshooting and repair of the disk type non-return valve
Maintenance, troubleshooting and repairs may only be executed by competent and trained staff.
Before starting maintenance, troubleshooting or repair work, the fittings must be rinsed with cold water for a
sufficient period in order to ensure that no cleaning products or hot water are left behind.
The valves are to be emptied thereafter.
Prior to the maintenance, troubleshooting and repair work, the operator of the system in which the disk type non-
return valves have been installed, must ensure that the fittings are de-pressurized and cannot be refilled with
agents or re-pressurized during the entire period of work.
The operator of the system in which the disk type non-return valves have been installed, must ensure that the
system area in which the maintenance, troubleshooting and repair work takes place, has been cordoned off against
access by unauthorized persons, and that the exclusion zone will be maintained during the entire period of work.
7.2.1. Seal gaskets
Practice-oriented maintenance intervals can only be determined by the respective user/operator because they depend
on the following application parameters:
Operating time per day
Switching intervals
Process parameter (temperature, pressure, flow)
Type of product (fat content, aromas, acids)
Type of cleaning (CIP / SIP / Disinfection)
Sealant
Maintenance intervals of 6-24 months are recommended as a standard value in compliance with the permissible pa-
rameters (see chapter "Permissible operating media, pressures and temperatures") and proper use.

8. Cleaning, disinfection
Cleaning and disinfection of the disk type non-return valves may only be done by competent and trained operating staff.
If the disk type non-return valves come into contact with food, the operator of the valves must prepare a maintenance
plan containing a system of measures to ensure that the required hygiene status of the fittings is maintained within
fixed intervals.
These measures include regular cleaning-in-place (short: “CIP”) of the valve interior. In some cases, this includes regular
“Sanitization-in-place" disinfection (short: “SIP“) of the valve interior.
It is characteristic of CIP and SIP processes that they must be carried out when the disk type non-return valves are
installed, e.g. together with a pipe cleaning or pipe disinfection or together with the cleaning or disinfection of the
system in which the valves are installed.
The disk type non-return valves must not be removed from the system in which they are installed for the purpose of
cleaning and disinfection!
Only permissible cleaning and disinfection media within the operating limits specified in chapter “Permissible operating
media, pressures and temperatures” may be used!
Recommended cleaning procedure:
Pre-rinsing (water) - alkaline cleaning - intermediate rinsing (water) - acid cleaning - rinsing (water)
Recommended procedure for chemical disinfection (only disinfect previously cleaned valves):
Pre-rinsing (water) - disinfection (chemical disinfection medium) - rinsing (sterile water)
Recommended procedure for thermal disinfection (only disinfect previously cleaned valves):
Rinse (water) - Drain - Disinfect (steam) - Condensate - Rinse (sterile water)
Recommended cleaning and disinfection parameters
(Temperatures, media, media concentrations, times, flow rates, clock cycles):
Flow rate: > 1.5 m/s
Media, media concentrations, media temperatures: Dependent on the type and extent of contamina-
tion, the sealing material in the valve and the fre-
quency of cleaning or disinfection
Cleaning and disinfection times: Dependent on the type and extent of contamina-
tion and the frequency of cleaning or disinfection
Operators and maintenance personnel should be instructed to wear appropriate protective clothing (e.g. gloves, gog-
gles) during automatic CIP and SIP processes!
The maintenance plans for cleaning and/or disinfection are to be validated by the operator of the disk type non-return
valves in accordance with their requirements.
9. Operating equipment and auxiliary media
9.1. External cleaner (foam, gel or spray cleaner for external cleaning of disk type non-return valves)
Compatibility of the external cleaner used with the surface materials of the disk type non-return valves (stainless
steels, plastics) must be ensured.

10. Decommissioning
Decommissioning the disk type non-return valves can be done with or without disassembly. In case of decommis-
sioning with disassembly, all disassembly steps described in the respective relevant operating instructions should
be additionally observed.
Before starting with a decommissioning, the disk type non-return valves must be rinsed with cold water for a suf-
ficient period in order to ensure that no cleaning products or hot water can be found.
The valves are to be emptied thereafter.
Prior to decommissioning without disassembly, the operator of the disk type non-return valves must ensure that
the fittings remain de-pressurized for a long time and cannot be refilled with agents or re-pressurized.
When decommissioning, physically separate disk type non-return valves from all media pipelines that could be
used to inadvertently supply media to the fittings!
11. Disposal
The disk type non-return valves must be disassembled in accordance with the disassembly steps described in the
operating instructions (See the “Disassembly – Assembly” chapter).
Dispose of disk type non-return valves according to local provisions and guidelines in country of use
