Process and Space Heating

A series of steam traps designed for fast start-up and modulating discharge with no live steam loss on service up to 30 psig differential. Ideal where a forged body with "Y" type strainer is required to handle light condensate loads including low pressure driplegs. The single blade element offers long-term, trouble-free service because it's not prone to dirt build-up as encountered with many other bimetal designs.

Features & Benefits
  • Maximum operating pressure: 30 psig (2,1 bar)
  • Stainless Steel internals – leads to longer service life since materials are highly resistant to fatigue and corrosion
  • Modulating discharge – automatically adjusts to operating pressure and load
  • Integral strainer and check valve – strainer protects trap from dirt while check valve prevents backflow during shutdown
  • Continuous air and CO2 venting – maximizes heat transfer while minimizing corrosion
  • Easy maintenance – traps are in-line repairable when isolated from live steam system and can be up and running again in minutes
