Our aseptic valves can be fitted with either PTFE bellows or metal bellows. This makes them equally suitable for aseptic and ultra-clean applications. We do not have an UltraClean valve range as our bellows technology offers both design and cost benefits. The complexity of the valves has been reduced so that aseptic process safety is maintained and faster and therefore more cost-effective maintenance is possible.
