Pratt LVC Figure 193 Bonneted Metal Seated Knife Gate Valve

  • Bonneted knife gate valves are ideally suited to reduce fugitive emissions and packing leakage.
  • Cast stainless steel body, gland, and yoke.
  • The wiper between the body and the bonnet prevents solids from entering the bonnet.
  • The bonnet design pressure same as the valve pressure rating of 150 PSI.
  • Standard TFE lubricated synthetic packing (TLSP) is 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 150 PSI rated pressure as required by MSS SP-81.
  • 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-duty cast stainless steel yoke prevents bending or twisting under extreme loads.
  • Easy conversion from handwheel operator to pneumatic or hydraulic cylinder, bevel gear, or electric motor operator using an existing cast yoke.
  • Enclosed bronze stem bushing reduces operating torque and protects the stem bushing in harsh
  • environments.
  • Hard-faced seat is available to prevent galling in a high cycle and/or high-end pressure or abrasive applications.
  • V-Port or O-Ring resilient seats are available to suit specific applications.
  • Precision-machined stainless steel gate provides superior seating capability.
  • Stainless steel stem provides corrosion resistance.
  • Flange drilling meets ANSI B16.5-150 LB standards with all tapped holes and serrated gasket faces.
  • Full port ID.
  • MSS SP-81 Stainless Steel, Bonnetless,
  • Flanged Knife Gate Valves.
  • AWWA C520-10 Knife Gate Valves, 2in.—96in.
