The CONBRACO 13-202-B10 is an ASME-certified low pressure steam heating relief valve designed for residential and light commercial steam heating systems. Built with a bronze body and threaded FNPT x MNPT end connections, it provides reliable overpressure protection on steam boilers operating at or below 10 psi. The valve is rated for a maximum working temperature of 250 degrees F and carries a capacity of 643 pounds per hour (PPH). Licensed plumbers and HVAC technicians install this valve as a required safety device on low pressure steam heating equipment certified to ASME Section IV standards.
This relief valve is suited for low pressure steam boiler applications in residential and light commercial settings. It fits a 1-inch inlet connection using standard FNPT x MNPT threading, making it compatible with typical boiler supply piping configurations. The bronze body construction resists corrosion in steam service environments. It is a direct-fit safety valve for systems governed by ASME Section IV low pressure steam boiler requirements and is commonly specified during new boiler installations or valve replacement service calls.
Designed as an OEM-style replacement or new-installation relief valve for low pressure steam heating boilers requiring ASME Section IV LP Steam certification at a 10 psi set pressure with a 1-inch inlet connection.
This valve must be installed by a licensed plumber or qualified HVAC technician in accordance with local codes and ASME Section IV requirements. Always shut down and depressurize the boiler completely before removing or installing any relief valve. The discharge port must be piped to a safe point of termination per applicable plumbing and mechanical codes. Never cap, plug, or restrict the discharge outlet of a relief valve.
