The Watson McDaniel IB1031 Series Inverted Bucket Steam Trap offers exceptional durability and reliable condensate removal for steam mains, drip legs, and tracing applications.
Resistant to Dirt and Debris: The discharge orifice is mounted at the top of the trap body, which prevents loose scale and dirt from easily clogging or damaging the valve and seat
Waterhammer Resistant: The rugged mechanical design stands up well against severe pressure shocks and waterhammer events common in industrial steam networks.
In-Line Repairability: All internal working components are attached directly to the cover, allowing technicians to service or repair the unit without removing the trap body from the piping.
Superheated Steam Capability: When equipped with an optional internal check valve, the trap maintains its water seal (prime) and handles superheated steam safely.
Long Operational Life: Stainless steel internals with hardened valves and seats reduce wear and extend service life far beyond many alternative trap designs.
Compact and Economical: As the smallest model in the Watson McDaniel Inverted Bucket Series, the 1031 handles pressures up to 150 PSIG and capacities up to 690 lbs/hr while fitting tight spaces with a 5-inch face-to-face dimension.
