Description

The Watson McDaniel IB1031-13-N-150 Inverted Bucket Steam Traps are used in drip applications to remove condensate from steam mains and steam supply lines. For drip applications, the smaller sized units have adequate capacity. The discharge orifice of the inverted bucket trap is mounted at the top of the trap body, which makes them less susceptible to failure from dirt and debris when compared to other trap types. Since Inverted Bucket traps have poor air-handling capability, they are normally not recommended for most process applications. However, they can be used on certain process applications such as unit heaters and laundry equipment, where discharging air during system start-up is not a critical factor. F&T traps are the preferred choice for systems where air must be quickly discharged.

When the trap is filled with condensate, the inverted bucket inside the steam trap loses its buoyancy and rests on the bottom of the trap. This pulls the disc off the seat allowing condensate to be discharged through the seat orifice located at the top of the trap. When steam enters, it fills the inverted bucket causing the bucket to float to the surface which closes the discharge valve, containing the steam in the system. Eventually, the steam is bled off through a small hole in the top of the bucket causing it to sink, which repeats the cycle.

IB Series Features:

  • Waterhammer resistant
  • Suitable for superheated steam (use internal check valve option to eliminate loss of prime)
  • In-line repairability is simplified by having all internals attached to the cover
  • Valve & seat are located at the top of the trap body making them less prone to clogging from debris and pipe scale
  • All stainless steel internals with hardened valve & seat

IB1031-13-N-150 Installation:

The trap must be installed in upright position to function properly. All working components can be replaced with the trap body remaining in-line. With superheated steam, a check valve should be installed at inlet or trap may lose prime. A replacement kit containing the lever and seat assembly is a more economical option than replacing the entire steam trap. Also available are replacement screens, gaskets and buckets. When ordering replacement lever and seat assemblies, specify model and operating pressure. See Replacement Parts and Kits Section for exact cross-reference to Armstrong PCA (Pressure Change Assembly) kits.
