GEA Tuchenhagen Leakage Valve ADV
ADV valves are the simplest form of aseptic leakage valves. The leakage chamber is created by two seals. Through the two side valves on the leakage chamber, the intermediate chambers can be steamed, the condensate drained, and leakage problems detected. The valve seats are moved using a pneumatic hoisting mechanism.
Housings for aseptic leakage valves are available with two, three or four port connections. The valves are produced with standard butt-weld connections by default. Mixed port connection sizes can be delivered upon request as well as various aseptic pipe connections.
The internal assembly has two screwed valve seat seals. The top one is made of Tefasep® (alternatively PTFE) and the bottom one of EPDM.
The standard version of the pneumatic actuator is designed as spring-closing / air-opening (NC). Alternatively, a variant with seat lifting function (AZ) is available.
Due to its solid construction, the clamp enables a pressure stable and safe connection of the main components. The special design with three segments allows a service-friendly handling of the component, even under tight space conditions.
Aseptic leakage valves can be either equipped with one or two side valves. Both of them are available in in the executions normally closed (NC) and normally open (NO). The valve seats of the side valves are hermetically sealed via a temperature resistant stem made of PEEK.
Aseptic shut-off valves can be either equipped with open feedback units or T.VIS® feedback systems by default. Feedback units from third party suppliers can be mounted via specially designed adaptors.
