USIB450 Inverted Bucket Trap Module

Horizontal Piping (Connector with Strainer)

Vertical Piping (Connector with Strainer)

DRIP, TRACING: The USIB450 inverted bucket steam trap modules must be mounted to a Universal Connector. They are typically used for drip applications such as draining condensate from steam mains or steam supply lines as well as for steam tracing applications. USIB450H is the higher capacity model.

All USIB450 modules mounts to any 2-bolt Quick-Change Universal Connector. Please refer to the Universal Connector product page.

Product Overview
DRIP, TRACING: The USIB450 inverted bucket steam trap modules must be mounted to a universal connector. They are typically used for drip applications such as draining condensate from steam mains or steam supply lines as well as for steam tracing applications. USIB450H is the higher capacity model. Steam trap modules can be used with other manufacturers’ Universal Connectors. See installation and Maintenance regarding using trap in superheated applications.
Features
• Trap module can be easily removed and replaced in minutes without having to disconnect any piping
• Hardened stainless steel valves and seat
• Freeze resistant
• Connectors available with integral strainers and blowdown valves
• 360º swivel design for convenient installation
How It Works
The UC450 universal connector is permanently installed into the pipeline where the steam trap would normally be placed. The trap module, which functions like any standard inverted bucket steam trap, is fastened to the universal connector with two bolts. When a new trap module is needed, it can be easily removed and replaced with a standard open-end or socket wrench without disturbing the existing piping.
Selection / Sizing / Capacities

From the capacity chart, select the model that can handle the working pressure of the system (PMO). Select the appropriate trap that will meet the capacity requirements at the differential pressure.

Example:

Application: 620lbs/hr at 50PSIG working pressure and 23 PSI differential pressure
Size/Model: USIB450H-70, at maximum working pressure at 70PSIG and 23 PSI differential pressure can handle the max condensate about 650lbs/hr.

Dimension and Weights
Options
Universal Connectors are available with an integral strainer and blowdown valve. Connector is purchased separately. See the UC450 Universal Connectors section for more information.
Installation and Maintenance
Universal connector is first permanently threaded or welded into piping system. The USIB trap module is attached to the universal connector with two bolts. When a new trap is needed, it can be easily removed and replaced with a standard open-end or socket wrench without disturbing the existing piping. Trap must be installed in upright position as shown to function properly. With superheated steam, a check valve must be installed at inlet of trap to prevent the loss of prime. In vertical piping installations with upward flow, use of a blowdown valve is not recommended because discharge would be in upward and possibly unsafe direction.
Sample Specification
The steam trap shall be an all stainless steel modular design, inverted bucket type with a frictionless valve lever assembly. The trap shall have a 360 degree swivel mount on a stainless steel Universal Connector that is available with integral strainer and blowdown valve options.
