The valve housing of the RIEGER aseptic valves is hermetically sealed from the environment and thus guarantees complete protection for your liquid product. The dead space-free design of the valve body and the optimum surface make them an indispensable component of sterile process engineering for food technology and pharmaceuticals.
Thanks to the modular system, the conversion from aseptic to hygienic design, from “air-opening” to “air-closing”, from liquid to fibrous and granular media is possible without any problems. The dimensions can also be adapted to the conditions on site.
Even under special conditions such as high sterilization temperatures, RIEGER aseptic valves meet all requirements for operational safety and reliable function.
