Metal-seated valves are heavier than resilient-seated ones due to solid wedge mass.

  1. Critical Notes & Selection Tips
  1. “Bronze Seated” Definition:
  • This data sheet now reflects a true Bronze-to-Bronze seal. The wedge has a Bronze ring/face that mates with the Bronze seat in the body. This is a metal seat, not a resilient seat.
  • Torque Requirement (Mandatory Gearbox):
    • Unlike soft-seal valves which rely on rubber compression, metal-seated valves require significant mechanical force to close tightly.
    • For a DN400 PN16 metal-seated valve, a gearbox (worm gear) is NOT optional – it is mandatory. Please confirm the gearbox ratio with the supplier.
  • Leakage Rate:
    • Metal-seated valves cannot achieve “zero leakage” (bubble tight) like rubber-seated valves. They typically conform to ISO 5208 Rate D (0.1x DN mm³/s) or Rate E. Please confirm the acceptable leakage rate for your application.
  • Приложение:
    • This bronze-on-bronze configuration is excellent for hot water, steam condensate, and some oil services where EPDM or NBR rubber would fail.

    Action Required:
    Please confirm with the manufacturer:

    1. Gearbox Ratio & Output Torque (Is it suitable for manual operation under max differential pressure?)
    2. Sealing Leakage Rate (ISO 5208 Rate D or better?)
    3. Flange drilling details (BS4504 PN16) to match your pipeline.
