Spirax-Sarco 64150 Bucket Trap

The Spirax-Sarco 64150 is a rugged B1H-125 Inverted Bucket Steam Trap engineered for high-efficiency condensate removal in industrial steam systems. Built with a heavy-duty cast iron body (ASTM A126 Class B), this 1/2" NPT mechanical trap is specifically designed for steam main drip stations, laundry equipment, and process heating applications. It features an in-line horizontal piping configuration, utilizing a stainless steel inverted bucket and a simple leverage system to ensure a cyclic discharge that minimizes live steam loss while effectively purging non-condensable gases. Rated for a maximum operating pressure of 125 PSIG at 450°F, the 64150 steam trap excels in handling dirt and water hammer, making it a reliable choice for veterans looking to reduce maintenance intervals. The internal stainless steel valve head and seat are hardened to resist wiredrawing and erosion, ensuring tight shut-off even under light load conditions. For peak performance, ensure the trap is primed during startup and consider installing a pipeline strainer upstream to protect the precision-lapped internals from scale and debris.

Key Benefits

• Enhanced Durability: The cast iron construction and stainless steel internals provide superior resistance to corrosion and hydronic shock.
• Optimized Performance: Efficiently handles air venting and non-condensable gas removal to improve heat transfer across the system.
• In-Line Maintenance: Designed for easy serviceability, allowing technicians to inspect and clean the mechanism without disturbing the horizontal piping.
• Versatile Application: Ideal for industrial dryers and storage tanks where robust condensate management is required at pressures up to 125 PSI.

Common Questions

How do I fix a loss of prime in the B1H-125?
Loss of prime typically occurs if the trap is oversized or if steam pressure drops rapidly. To restore functionality, isolate the Spirax-Sarco 64150 and manually add water to the trap body to re-establish the water seal around the inverted bucket.

Can this trap be used in superheated steam applications?
Yes, however, a check valve must be installed at the inlet to prevent the loss of the water seal (prime) when used in superheated conditions or systems with modulating pressure.

What maintenance is required for the 64150 model?
Periodic inspection of the valve head and seat for wear is recommended. The bucket vent hole must remain clear to ensure the bucket can fall and open the valve; if it becomes clogged, the trap may fail in the closed position.
