Knife
gate valve is designed to handle slurries, including fibrous material.
The valve owes its ability to handle these fluids to the knife-edged disc,
which is capable of cutting through fibrous material, and the virtual absence
of a valve body cavity. The disc travels in lateral guides and is forced againstthe seat by lugs at the bottom. If a high degree of fluid tightness is equired,
the valve may also be provided with an O-ring seat seal.
Features
• Meets a wide range of abrasion, corrosion,
temperature, and pressure requirements.
• May be used in wet or dry services easily
dealing with large, heavy particles and tramp
material.
• Heavy-duty, field replaceable elastomer
sleeves with internal stiffener (U. S. patent
5,271,426).
• No metal parts in contact with the flowing
slurry.
• Unobstructed flow eliminates turbulence,
minimizes pressure drop across valve.
• 100% Isolation; bubble-tight shut-off results
in absolutely zero downstream leakage.
• Double-seated design provides bi-directional
flow and shut-off.
• No seat cavity where solids can collect and
prevent full gate closure.
• No gate or stem packing is required,
eliminating packing leakage and
maintenance.
• Adaptable frame (yoke) design featuring a
top-removal stem nut.
