Knife Gate valvesFeatures and Benefits

  • Knife Gate conforms to TAPPI TIS 405.8 face to face
  • Knife Gate flanged ends meet ASME B16.5 and design test to MSS - SP81
  • Full lug pattern. Drilled and tapped to suit ANSI Class 150 Flanges (1050 KPA)
  • Solid, all one-piece cast stainless steel valve body, yoke and packing gland. The one piece design eliminates twisting/deflection that is encountered on a multiple post design.
  • Easy bolt-on conversion to Actuator or Bevel Gear Operator
  • PTFE impregnated packing suitable for temperatures up to 450°F / 232°C and a PH of 2 - 12
  • Machine ground gate and lapped integral metal seat are designed to handle dense mixture of stock and slurries. The pure shearing action of the K.G. Knife cuts through solids and the venturi effect cleans the seat close
  • The uni-directional metal seated valve has fully guided gate at 180 degrees and jambs at the bottom for the correct position on the gate against the seat. Fluid pressure assists sealing capacity.
  • The two-way resilient seated valve provides bubble tight shut off in both directions
  • The Knife Gate Resilient Seated Valve is supplied standard with viton resilient seat good for temperatures up to 300°F / 150°C with PTFE adjustable packing pusher
  • The standard resilient seat "viton" is excellent for aging, sunlight resistance, water resistance, oil resistance, medium acid, and PH from 2 - 12 @ Universal Seat
  • Resilient Seat is a positive retained seat that will not pull or roll over. No grooves or pockets to collect product, plus a backup secondary metal seat between the disc and body seat. True 100% full bore design.
  • The edge on the resilient seat maintains the same shearing action as the metal seat to handle dense pulp stock and other slurries with a self-cleaning action to maintain bubble tight shut-off.
  • Multiple packing with true leveling stainless steel gland bolts and self-locking nuts
  • One-piece stainless steel stem and thrust bearing to assist closure of handwheel - low torque, reduces rim pull
  • Bonnetless design-O.S.Y. non-rising handwheel with a handwheel lockwasher which endures high vibration
