GEA’s hermetically sealed control valve extends shelf life of food and beverages
GEA is expanding its D-tec valve line with the new GEA D-tec P/DV control valve for ultraclean applications in the food, beverage and dairy industries. This allows reliable control of process parameters such as volume flow, pressure, temperature and filling level of a vessel. Due to the hermetically sealing D-tec stem diaphragm, the valve achieves a higher standard of hygiene. For example, it helps ensure product safety in beer mixes and soft drinks, fruit juices, milk-based and lactic acid-fermented products or sauces, and contributes to a longer minimum product shelf life as is often demanded by the market.
Longer shelf life, less preservatives
The P/DV type D-tec control valve uses hermetically sealed D-tec stem diaphragms. These provide improved contamination protection against the atmosphere and thus ensure microbial stability of the product throughout the entire process. While the D-tec valve line can be used in aseptic processes, GEA sees the application of the new control valve primarily for ultraclean applications. The control valves are selected for products that require an extended shelf life, with or without cooling, depending on the pH value, cold chain and storage characteristics. These products include iced tea, fruit juice, fruit yoghurt and ESL milk.
