FT600 (Cast Steel) 3″ – 4″ Steam Traps

FT600 (Cast Steel) 3″ – 4″ Steam Traps with Carbon Steel Body and in-line repairable connectors were specifically designed for removing condensate and air from higher pressure steam applications or where steel bodies are specified. They are typically used in chemical plants and petrochemical refineries on re-boilers, heat exchangers, and other critical process applications. The excellent air-handling capability of float and thermostatic traps make them a better choice than bucket traps for applications requiring quick system start-up. Maximum steam pressure is 450 PSIG. These models contain an open orifice air vent. If a thermostatic air vent is required, contact factory.

  • Investment cast steel body and cover with class 400 shell rating (670 PSIG @ 750 °F)
  • Hardened stainless steel seat and disc for extended service life even at extreme temperatures and pressures
  • Excellent air handling capability allows air to be discharged rapidly so steam can enter the system quickly during start-up
  • In-line repairability is simplified by having all internals attached to the cover. Studded cover allows for easier removal of body.
  • Welded stainless steel air vent resists shock from waterhammer. Live orifice air vent is available for superheated applications
  • F&T traps discharge condensate immediately as it is formed (no condensate will back up into the system)

Description

FT600 (Cast Steel) 3″ – 4″ Steam Traps with Cast Steel Body and in-line repairable connectors were specifically designed for removing condensate and air from higher pressure steam applications or where steel bodies are specified. They are typically used in chemical plants and petrochemical refineries on re-boilers, heat exchangers, and other critical process applications. The excellent air-handling capability of float and thermostatic traps make them a better choice than bucket traps for applications requiring quick system start-up. Maximum steam pressure is 450 PSIG. These models contain an open orifice air vent. If a thermostatic air vent is required, contact factory.

Float and thermostatic traps contain a float and seat mechanism with a separate thermostatic element which work together to remove both condensate and air from the steam system. The float, which is attached to a valve, rises and opens the valve when condensate enters the trap. This allows the condensate to discharge. Air is discharged through the thermostatic air vent to the outlet side of the trap. Steam entering the trap causes the thermostatic element to expand, closing the air vent and trapping the steam.

Live orifice air vent for superheated applications.
