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

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.
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.
