The PT series knife gate is a bi-directional through going wafer valve, soft or metal-metal seated, equipped with two adjustable stuffing boxes. Valve designed to handle media with high consistency, mainly used on industrial bulk and paper applications.

Sleeves (DN50-DN300) and packing materials can be replaced without valve disassembly from the pipeline.
General information
Valve features and benefits:
  • Bi-directional
  • Two split bodies, wafer-design
  • Through going gate
  • Adjustable two stuffing boxes, allowing packing materials replacement without valve disassembly
  • Two sealing systems:
    • DN50-DN300: two sleeves (tight version) or two metallic rings (metal-metal valve). Same valve can be used for both options. Sleeves can be replaced without valve disassembly from the line
    • DN350-DN600: two profile o-rings (tight version). Metal-metal seated valve without elastomeric parts on the passage. Profile o-rings cannot be replaced without valve disassembly from the pipeline
  • Short face-to-face dimension
  • Easy drive replacement
  • Proximity and limit switch mounting points

Application fields:
  • Pulp and paper
  • Mining
  • Bulk handling
  • Food and beverage
  • Chemical process
  • Etc.
