WT2500 Repairable Cast Iron Steam Traps

DRIP, TRACING, PROCESS: WT2500 Repairable Cast Iron Steam Traps are used for drip, tracing and process applications. Their compact size, excellent air handling capability and wide operating pressure range make them a great choice for most applications. Thermostatic traps are far superior to bucket traps and thermodynamic disc traps in their ability to remove air from the system.

WT2501 refer to 3/16″ orifice size, WT2503 refer to 5/16″ orifice size.

Catalog Spec Sheet



WT2500 Repairable Cast Iron Steam Traps are extremely energy efficient and excellent at discharging air allowing steam to enter the system quickly during system startup. Models are available in Stainless and alloy steel for Drip, Tracing, and medium size Process applications. Pressures up to 650 psig.

  • Superior air venting capability and extremely energy efficient
  • Single model operates over the entire pressure range in contrast to (F&Ts & IBs)
  • Considerably Smaller in size than F&Ts & IB traps of similar capacities
  • Self-draining to prevent freezing (unlike F&Ts and IB traps)
