RIEGER DD double seal valves are used for the mixproof shut-off of product and cleaning medium in pipe sections. The leakage chamber is located between the separating seals. The leakage is discharged to the outside via the leakage valves.
The design of the one-piece, solid and cavity-free valve housing offers optimum CIP/SIP cleaning options. The valves are used in systems in the brewing and beverage industries, in dairies and in the food and pharmaceutical industries.
