MG SERIES
Knife gate valves with an EN 558/ISO 5752 20 series face to face often quickly reach their pressure limit values of 10 bar – but not our MG series. For the same face to face, it is generally designed for pressures of up to 16 bar. Of course, we retained the many design features that have always set the Wey knife gate valve apart from the competition.
