Mixproof valves are used for mixproof separation of incompatible media at flow path intersections within the pipe system.
Over 40 years ago, founder Otto Tuchenhagen invented the first mixproof valve – a development which immediately allowed plants to be designed and operated in a flexible, sanitary and safe manner at the highest level of efficiency.
In April 2007, in perhaps the greatest breakthrough in US dairy plant design in 25 years, GEA Tuchenhagen’s 24/7 PMO ValveŽ became the first mixproof valve to be authorized by the US regulatory authorities to be cleaned while simultaneously processing product.
Overnight this valve has changed the way US dairy plants are designed and operated.
