Conbraco 13211B15 Steam Boiler Safety Valve

The Conbraco 13211B15 Steam Boiler Safety Valve provides reliable overpressure protection for low-pressure steam systems. This lever-handle, safety valve features a 3/4 inch inlet and 3/4 inch outlet with a male x female threaded end connection, making installation straightforward on standard steam piping.

Built for durability, the bronze body (ASTM B584) combines with a stainless steel spring, EPDM seal, and a PTFE-coated disc to resist corrosion while maintaining a positive, dependable seal. The flat seat with a PTFE-faced disc ensures a tight closure and positive drainage of condensate away from the seat area. Set at 15 PSIG with a temperature rating of 250°F, it is ideal for low-pressure steam heating and supply boiler applications.

Trusted for safety and performance, this valve complies with ASME and ISO 9001 standards and carries CRN 0G8547.5C HV NB, delivering consistent operation across commercial and industrial environments. Its capacity is 475 pounds per hour, providing reliable relief when needed.
