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.
When plant-forward South Korean food producer Pulmuone brought GEA the challenge of developing a modern spin on the traditional chewy cold (naengmyeon) noodle, GEA’s R&D experts were up to the challenge. They helped develop what is now a commercial hit produced with less water and electricity than previously existing methods. The result is also true to the traditional origins of the dish as well as Pulmuone’s health, well-being and sustainability roots.
GEA's innovative process marks a milestone in the pretreatment of biofuels such as hydro-treated vegetable oil and sustainable aviation fuel. By eliminating the bleaching process, manufacturers benefit from significant savings potential: over 50% lower operating costs and up to 12% less CO2 emissions.
