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.

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.
