DANGER
Hazards resulting from pollution or contamination caused by the use of
non-permissible media in the valves or
due to improper cleaning or
improper disinfection
of the valves and which can lead to an adverse effect on the processed foods in the valves.
Examples:
Substances which result from corrosion
Residues of cleaning media
Residues of disinfection media
Failure to comply with the hygiene instructions
Risk of accidents
severe injuries may occur

Place of use, environment
The disk type non-return valves are mainly used in breweries, as well as the food and beverage, and pharmaceuti-
cal, chemical and cosmetic industries.
They are used in service room locations with floors resistant to acids and alkalis.
The locations must be equipped with normal room lighting so that the labels and warning signs on the valves are
clearly visible at all times.
Permissible ambient temperature: -10 °C – +55 °C
Air humidity: 100% relative up to a temperature of 25 °C.
Wet area.

Spatial and procedural limits
The disk type non-return valve described here generally extends in terms of space up to the pipe connections, as
illustrated in the following dimensional drawings.
Welded process connectors that are not explicitly illustrated are not included for calculating the spatial contents
of the fittings.
Spatial and process engineering limits of the disk type non-return valves are diagrammatically presented in the
chapter “Technical Data”.

Operating media and operating limits
Permissible minimum temperatures for operating media:
Disk type non-return valve with the sealing material EPDM
≥ -10.0 °C
for gases
≥ -10.0 °C
for fluid media with freezing point ≤ -10 °C
> 1.0 K above freezing point
for fluid media with freezing point > -10 °C
Disk type non-return valve with the sealing material FKM
≥ +1.0° C
for gases
≥ +1.0 °C
for fluid media with freezing point ≤ 0° C
> 1.0 K above freezing point
for fluid media with freezing point > 0° C
Maximum permissible operating pressures in connection with permissible operating media, maximum permissible
operating temperatures and the applicable sealing materials at the “Product connections” process engineering
interfaces are shown in the chapter "Permissible operating media, pressures and temperatures”.
