Spirax-Sarco B1H-75 Inverted Bucket Steam Trap Overview
The Spirax-Sarco B1H-75 (SKU 64149) is a heavy-duty inverted bucket steam trap engineered for dependable condensate removal in industrial and commercial steam systems. Rated at 75 PSI with 1/2″ pipe connections, this trap delivers the proven performance and long service life that Spirax-Sarco is renowned for worldwide.
How It Works
The inverted bucket mechanism operates on the principle of buoyancy. When steam enters the trap body, the inverted bucket floats and holds the valve closed, retaining live steam. As condensate accumulates and fills the trap body, the bucket loses buoyancy, sinks, and opens the valve to discharge condensate — then closes again when steam re-enters. This continuous, intermittent cycling ensures efficient condensate removal while preventing steam loss.
