Resilient Seated Knife Gate Valve


  • Heavy duty cast ductile iron body, packing gland, and yoke for the most rugged service.
  • Through bolting on side flange bolts allows easy installation.
  • Easily replaceable natural rubber, EPDM, or BUNA-N seat provides a bi-directional drip tight seal across the gate from 0 to 150 PSI. Contact factory for service limits.
  • Seat is flush with the bottom of the port eliminating pockets in the bottom of the valve that may collect material in media such as slurries, pellets or powders.
  • Rubber seat has a molded-in steel reinforcement and is bolted in place to prevent shifting out of position by gate movement.
  • Machined stainless steel gate provides corrosion resistance and durability.
  • Easy conversion from handwheel operator to hydraulic or pneumatic cylinder, bevel gear, chain wheel, electric motor, or fail safe spring cylinder operator using existing cast yoke.
  • Enclosed bronze stem nut provides reduced operating torque and is protected from harsh environments.
  • Stainless steel stem resists corrosion.
  • Full packing seal around gate minimizes the potential for packing leakage.
  • MSS SP-81 and AWWA C520 face-to-face and flange dimensions.
  • Minimum 4 bolt packing gland to ensure proper gland alignment in all valve sizes.
  • Entire valve (inside and outside) is epoxy powder coated to provide corrosion resistance.
  • CRN Registered
