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.

Face to face dimension
-
The gate is mechanically guided over the full stroke.
-
The transverse seal can be repacked at any time and under full pressure using the lateral packing screws.
-
Robust 4-post topwork for maximum load and a wide variety of actuator types.
-
Optimized chest design to minimize the build-up of solids due to gate geometry.
