Bonneted Knife Gate Valve


  • Fabricated heavy duty bonneted knife gate valves are ideally suited to reduce fugitive emissions and packing leakage.
  • All stainless steel construction available.
  • Wiper between body and bonnet prevents solids from entering bonnet.
  • Fabricated bonnet design pressure same as valve pressure rating.
  • Standard TFE lubricated synthetic packing (TLSP) rated for 500° F and a pH range of 3-11.
  • Heavy duty body design resists deflection from line loads and internal pressure. 
  • Gate design withstands full rated pressure.
  • Body cavity, seat configuration, and beveled gate design provide shut off capability in thick media such as pulp stock and slurries, or solid media like pellets and powders.
  • Heavy fabricated steel yoke prevents bending or twisting under extreme loads.
  • Easy conversion from gear operator to pneumatic or hydraulic cylinder, or electric motor operator using existing cast yoke.
  • Hard faced seat available to prevent galling in high cycle and/or high end pressure or abrasive applications.
  • V-Port or O-Ring resilient seats available to suit specific applications.
  • Precision machined stainless steel gate provides superior seating capability.
  • Stainless steel stem provides corrosion resistance.
  • Flange drilling meets ANSI B16.47 CL150 series A standards with all tapped holes and serrated gasket faces.
  • Full port ID.
  • Designed in accordance with AWWA C520 Knife Gate Valves, 2” – 96”.
