The MU series knife gate is a uni-directional wafer valve, soft or metal-metal seated, equipped with adjustable stuffing box. Valve designed to handle pulp, arid and powder mediums, mainly used in industrial bulk and silo outlet applications.

Sleeve (DN50-DN300) and packing material can be replaced without valve disassembly from the pipeline.
General information
Valve features and benefits:
  • Uni-directional
  • Monoblock one-piece body: semi lugged (wafer) and optionally, fully lug-between flanges and fully lug-end
  • Adjustable stuffing box, allowing packing material replacement without valve disassembly
  • Two sealing systems:
    • DN50-DN300: sleeve (tight version) or metallic ring (metal-metal valve). Same valve can be used for both options. Sleeve can be replaced by only holding the valve on one bolt and rotating 90º. Warning: sleeve seated valves designed only for flanges DN2632
    • DN350-DN600: profile o-ring (tight version). Metal-metal seated valve without elastomeric parts on the passage. Profile o-ring cannot be replaced without valve disassembly
