BONNETED KNIFE GATE VALVE

 
- Bonneted Knife Gate Valves are ideally suited
  to aid in reduction of Fugitive Emissions.
- Cast stainless steel body, gland and yoke.
- Fabricated bonnet which can be designed to  
  the full pressure rating of the valve. 
- Wiper between body and bonnet to prevent               
  solids from entering bonnet.
- Maintenance free Viton stem seal with packing-
  less O-ring seal gland design.
- Heavy duty designed body to resist deflection 
  from line loads and internal pressure.
- Gate designed to withstand full 150 PSI rated 
  pressure as required by MSS-SP-81.
- Body cavity, seat configuration and beveled 
  gate designed to provide shut-off capability 
  in thick media such as pulp stock, slurries, or
  with solid media such as pellets or powders.
- Heavy duty cast stainless steel yoke will not
  bend or twist under extreme loads.
- Easy conversion from handwheel operator to 
  cylinder, bevel gear or electric motor operator
  using cast yoke.
- Enclosed brass stem bushing provides reduced
  operating torque and protection of the stem 
  bushing from harsh environments.
- Hard faced seat available to prevent galling 
  in high cycle and/or high end pressure 
  applications or abrasive applications.
- O-Ring resilient seat available.
- Precision machined stainless steel gate for 
  superior seating capability.
- Stainless steel stem for corrosion resistance.
- Designed and tested to MSS-SP-81 dimensions
  and specifications.
- Full port ID.
