With a 1″ inlet and 1-1/4″ outlet configuration, an 80 PSI set pressure, and a rated capacity of 3,381,000 BTU/hr, this valve is built to handle demanding commercial and residential heating applications with confidence.
Conbraco’s 10-600 series relief valves are trusted throughout the HVAC and hydronic industry for their consistent performance, durable construction, and compliance with industry safety standards.
