UB450 Bi-Metallic Trap Module

DRIP, TRACING: The UB450 steam trap module are used in steam tracing applications (fro process line heating, instrumentation and winterization, general steam jacketing ). In tracing  applications, the externally - adjustable ( temperature adjustment) bi-metal element provides accurate control of condensate discharge temperature as required to maintain a specific product temperature as well provide maximum usage of energy.

The UB450 trap module mounts to any Universal Connector. Please refer to the Universal Connector product page.

Product Overview
The UB450 Series Bi-Metallic Steam Trap Modules are used in steam tracing applications (for process line heating, instrumentation and winterization, general steam jacketing). In tracing applications, the externally-adjustable (temperature adjustment) bi-metal element provides accurate control of condensate discharge temperature as required to maintain a specific product temperature as well provide maximum usage of energy.
Features
• Excellent for various steam tracing and small process applications where maximum energy usage is desired
• Field-adjustable bimetal element allows control of ondensate discharge temperature, providing maximum use of additional energy in the condensate
• Internal screen and seat/plug design help prevent pipe scale and debris from accumulating on seating surfaces to provide trouble-free operation
How It Works
Bi-metallic plates of dissimilar metals which are connected to the valve seat assembly respond to temperature variations. At relatively cool conditions, the trap is open for the discharge of condensate. When the temperature of the condensate is equal to or higher than the set temperature, the metals react and expand, closing the trap. External field-adjustability of the bi-metal element allows control of the condensate discharge temperature. Trap module is fastened to the universal connector using 2 bolts.
Selection / Sizing / Capacities


Note:  1) Capacities in chart are based on discharging condensate to atmosphere with a condensate temperature of 200° F.
  2) Contact factory for additional information including other condensate set and discharge temperatures.
  3) To ensure proper operation and eliminate possible steam loss, the Set Temperature should be lower than 27 °F subcool (degrees below inlet steam saturation temperature).
Dimension and Weights
Installation and Maintenance
Universal connector is first permanently installed (threaded, welded, flanged) into piping system. Trap module should be installed in orientation shown with cap facing upwards. The trap module is fastened to the universal connector using two bolts. If the trap fails for any reason, replace only the trap module. In vertical piping installations with upward flow, use of a blowdown valve is not recommended. Discharge would be in upward and unsafe direction.
