Millipore launched aseptic valves with PTFE diaphragms. The thermal and chemical durability of PTFE makes it an ideal material for diaphragms in demanding multi-product processes. The spring closed valve seal for PTFE diaphragms is based on a forced cup spring technology, which applies pressure over the diaphragm seat and maintains this pressure over time. This technique reduces the maintenance needs with prolonged life time. NovAseptic valves are available in sizes 0.5 to 3” and are used in a wide range of process applications. The aseptic design of the valves eliminates deadlegs and minimises product hold-up, which facilitates a safe and cost-efficient production. In addition, the valves are easily cleanable- and sterilisable-in-place (CIP/SIP).
