SPECIFICATIONS:
  • “Industry Standard” valve sizing currently offering 3.75”-4.00” and 4.50”-5.00” sizes.
  • Single piece 8620 casting, machined to strict tolerances.
  • Valve surface hardened (carburized) for prolonged wear.
  • Valve designed using Finite Element Analysis (FEA) software and fully tested via computer model.
  • Independently field tested.

FEATURES:
  • Legs have been tapered.
  • Legs have large “guide” pads.
  • The Dragon Gray Bonded Valve is a MDI/Polycaprolactone compared to the STD MDl/Polyester.
  • Our Gray Bonded Valve is good to 225°F compared to the STD 180°F.
  • Operates in conditions up to 28% HCL.

BENEFITS:
  • Better flow characteristics
  • Valve remains centered in the seat. This ensures the urethane makes a symmetrical seal each time it contacts the seat. Un-even sealing causes the urethane to fail prematurely.
  • Will yield improved abrasion properties.
  • Equals higher temperature applications.
  • Will not swell as the STD MDl/Polyester does in very small concentrations of HCL.
