- 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.
