UltraClean double-seat valves are used for the mixproof shut-off of incompatible products at pipe junctions in processing plants. The moving valve stems are sealed by hermetic sealing elements and depending on the required level of product safety, the area between the two product lines is either executed as a leakage area or as a sterile barrier.
The two valve lines distinguish themselves via the hermetic sealing concept. The Aseptomag® valve line is based on stainless steel bellows technology, where the D-tec® valve line uses stem diaphragm technology to hermetically seal the sterile process pipe against the atmosphere. Both valve lines are mainly used for dairy, beverage and food applications.

Double-chamber valves of the D-tec® valve line are characterized by their hermetically sealing stem diaphragm design. The valve type D/DV includes one sterile barrier (ISB).

Leakage valves of the Aseptomag® valve line are characterized by their uncompromising stainless steel bellow design. With their leakage area between the two valve seats open to atmosphere, the valve is an ideal fit for UltraClean mixproof applications.
At Carlsberg’s Fredericia brewery, GEA VARIVENT valves are part of a long-game strategy. By reusing core valve bodies, retrofitting actuators and control tops, and planning maintenance around brewing seasons, Carlsberg extends asset life, reduces downtime and supports its ambitious water and sustainability targets.
