Spirax Sarco B1H

Steam Trap

Spirax Sarco B series steam trap operates using an inverted bucket mechanism that responds to the density difference between steam and condensate, providing reliable cyclic discharge. Condensate is removed at a temperature close to that of saturated steam, ensuring efficient system operation and effective condensate management.

The trap features a robust cast iron body combined with stainless steel internal components, including a stainless steel bucket, for durability and long service life. Optional configurations are available with an integral strainer and/or bimetallic air vent to suit different installation and operating requirements.
