Bonneted Knife Gate Valve

Specifications:

• 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.
