18 Sep 2018 --- 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 is said to achieve a higher standard of hygiene. The company touts the valve as ensuring safety in the production of beer mixes, soft drinks, fruit juices, milk-based and lactic acid-fermented products or even sauces and to contributing to longer minimum product shelf life.
