Double seal valve DD – hygienic

 

 
RIEGER Double Seal Valves DD (DN 40-100) are used for the mix-proof barrier of product and cleaning medium in pipe sections.

The leakage chamber is placed between the separating seals. The leakage is discharged via the leakage valves to the outside. 
 
The design of the one-piece, solid and cavity-free valve housing provides optimal CIP/SIP cleaning options. The valves are used in systems of the brewery and beverage industry, in dairies and in the food industry and pharmaceutical industry.
