GEA is launching its D-tec D/DV double-chamber valve, designed with a sterile leakage chamber which is hermetically sealed from the atmosphere by two side valves. As with the entire aseptic range, sealing properties of the new valve stem diaphragm raise hygiene standards to an UltraClean level, thus increasing the shelf life of soft drinks, fruit juices, as well as milk-based and lactic acid-fermented products.
If manufacturers adapt their process chain accordingly, the valve can help them achieve a desired shelf life with fewer preservatives. With the double chamber valve, the firm offers aseptic valves for both hygiene classes Aseptic and UltraClean, which are tailored to the special conditions of the respective applications.
This valve is suitable for iced tea, fruit juice, fruit yogurt and ESL milk and products that require an increased shelf life depending on the pH value, cold chain and storage conditions. Like the entire range, the D/DV double-chamber valve is based on the tried and tested Varivent assembly unit, which is characterized by its adaptability. This enables the valve to be configured according to the required process conditions. The double-seat valve is characterized by the two membranes, which hermetically seal the product interior from the atmosphere.
It is available in valve sizes ranging from DN 40 up to DN 80 and OD 1.5 up to OD 3″. The valve seat can be executed as both soft and hard sealing, the latter with the Tefasep gold seal.
