Overflow valve US – hygienic

 

 

 

RIEGER Overflow valves US open the set response and thus prevent unwanted pressures in pipelines .

They are available with weld ends and with dairy screwings or clamp ferrules.

One possible application is the protection of forced-feed pumpsperistaltic pumps.
 
The overflow valve US is suitable for all liquid media.

Overflow valves are no safety valves..

For this purpose we recommend the TÜV certified safety valve type SH.
