FIGURE 77 Resilient Seated Knife Gate Valve

Cast stainless steel body, packing gland, and yoke.
Rubber seat provides a BI-DIRECTIONAL drip-tight seal across the gate from 0 to 150 PSI.
Gate design withstands full 150 PSI rated pressure as required by MSS SP-81.
Bi-directional Buna resilient seat standard.
Also available in EPDM, Viton, Neoprene, and other materials.
FIGURE 77 Resilient Seated Knife Gate Valve Compact wafer configuration to TAPPI and MSS standard face-to-face.
Heavy-duty body design resists deflection from line loads and internal pressure.
The rubber seat is flush with the bottom of the port ELIMINATING any pockets in the bottom of the valve that will collect media material.
Smooth flow non-clogging full port design.
Heavy-duty cast stainless steel yoke will not bend or twist under extreme loads.
Easy conversion from handwheel operator to hydraulic or pneumatic cylinder, bevel gear, chainwheel, electric motor, or fail-safe spring cylinder operator using an existing cast yoke.
Bonnetless, outside screw and yoke, non-rising handwheel, and rising stem.
Enclosed bronze stem bushing provides reduced operating torque and protection of the stem bushing in harsh environments.
Stainless steel stem resists corrosion.
Standard TFE lubricated synthetic packing (TLSP).
