10. General Notes

  1. Concentric design means the shaft is centered in the disc and body, offering compact face-to-face and low weight.
  2. Replaceable EPDM/NBR seats wrap around the body chest, isolating fluid entirely from the cast iron body.
  3. Lugged style valves are recommended for dead-end piping services to permit downstream pipe dismantling.
  4. Potable water valves are coated with non-toxic, electrostatic epoxy powders (min 250 μm thickness).
