SER300 – Scavenger Valve

Recycle Mill – Heavy Trash Applications

Features and Benefits

BidirectionalPS

  • Perimeter seating guarantees bi-directional bubble tight shutoff. Cavity free body design prevents de-watering of pulp stock and is ideal in slurries, powders, plastics and other solids handling applications
  • Addition of Cone Deflector protects and extends the integrity of the perimeter seat in heavy solids, slurries and abrasive applications
  • Elastomer seat is mechanically retained between body halves preventing movement or separation from the body, unlike standard o-ring seated valves
  • Precision machined body halves serve as scrapper blades, which clean the gate and extend the life of the packing system
  • Two-piece body design simplifies repair / replacement of gate, packing, seat ring and topworks assembly
  • ALL NPV/DUCO Valve body castings are of 317SS (CG8M). Cone deflectors are available in 317SS, 400SS heat treated and hardened and polyurethane
  • All external valve components – stanchions, bolting, bridge, stem, clevis, packing follower – are stainless steel construction which eliminates external corrosion
  • Precision machining of the stuffing box with the live-loaded packing in conjunction with an additional Viton O-ring provides for a very dependable and adjustable packing system
  • Two piece body design allows for option to use the standard perimeter seat or replaceable cartridge seats depending on requirements of application

Typical applications include:

  1. Wet and Dry ash
  2. Pellets and granules
  3. Plastic chips
  4. Slurries with heavy solids such as lime slurry, lime mud, animal rendering plant waste and raw sewage
