FDA500 Clean Steam Traps

FDA500 Series thermostatic clean steam traps are used in clean steam applications as drip traps on piping runs as well as for drainage for CIP/SIP  systems and various process vessels. Available with 2°F sub-cool bellows.

  • All wetted parts are 316L stainless steel
  • Electro-polish finish of 20-25 microinches RA on internal surfaces of body. Consult factory for 15RA max surface finish option.
  • Electro-polish finish of 25-32 microinches RA on external surfaces of body
  • Operates close to saturation curve to minimize condensate back-up
  • Completely self-draining in the vertical downward flow orientation


FDA500 Clean Steam Traps are used on:

  • clean steam applications
  • drip traps on piping runs
  • drainage for CIP/SIP systems
  • various process vessels
This trap contains a welded 316L stainless steel thermal element that expands when heated and contracts when cooled. When air and sub-cooled condensate are  present, the trap is in an open discharge position. When steam reaches the trap, the element expands, closing the trap tightly.
