Spirax-Sarco 64160 Trap

The Spirax-Sarco 64160 (Model B1H-30) is a heavy-duty 3/4" inverted bucket steam trap engineered for reliable condensate management in high-demand process environments. Featuring a rugged cast iron body (ASTM A126 Class B) and a corrosive-resistant stainless steel mechanism, this trap utilizes a simple, robust leverage system to handle pressure differentials up to 30 psig. The in-line horizontal configuration simplifies installation on steam main drip stations, laundry equipment, and industrial dryers. Designed to resist water hammer and hydronic shock, the B1H series steam trap operates with a cyclic discharge action, ensuring condensate is removed at temperatures close to steam saturation. The hardened stainless steel valve head and seat provide superior longevity in scaling or dirty conditions, maintaining a tight shut-off even under light load applications. Whether you are servicing storage tanks or heat exchangers, this mechanical steam trap offers a high capacity of approximately 1,000 lbs/hr, making it a staple for any industrial steam system maintenance professional.

• Exceptional Durability: The ASTM A126 cast iron construction combined with stainless steel internals ensures resistance to erosion and corrosion.
• Water Hammer Resilience: The inverted bucket mechanism is naturally buoyant and handles sudden pressure surges better than float-type or thermostatic alternatives.
• Low Maintenance Design: All internal components are accessible for inspection or replacement without disturbing the existing pipework.
• Effective Air Venting: Standard internal bucket vents allow for the continuous discharge of non-condensable gases to prevent air binding.
• Versatile Application: Ideal for steam main drips and equipment where dirt or scale might overwhelm smaller trapping units.

What is the maximum operating pressure for the B1H-30?
The "30" in the model name identifies that this specific unit is rated for a maximum operating pressure (PMO) of 30 psig. Operating above this limit may prevent the trap from opening against the internal pressure differential.

Can this trap be installed in vertical piping?
The B1H unit is designed specifically for horizontal in-line installation. The bucket must rise and fall vertically to function, so the trap must be mounted level to ensure a proper water seal and prevent steam blow-through.

Does this model include an integrated strainer?
This specific model (64160) is the standard B1H-30. While it is highly resistant to dirt, standard best practice for an inverted bucket trap includes installing an upstream Y-strainer to protect the valve seat from large pipe scale.
