Conbraco 10-616-12 Valve

The Conbraco 10-616-12 boiler pressure relief valve is a high-capacity safety control engineered for large-scale commercial and industrial hot water heating systems. Featuring a 1-1/4 inch FNPT inlet and a 1-1/2 inch FNPT outlet, this bronze-body valve is factory set at 60 PSI to prevent over-pressurization in high-output boilers. With a verified discharge capacity of 4,596,000 BTU/hr, it meets ASME Section IV requirements for pressure vessel safety. The Apollo 10-600 series design utilizes a high-lift disc and an EPDM o-ring for a positive seal, ensuring reliable operation under heavy thermal cycling. For technicians servicing large hydronic loops, this valve provides the necessary BTU relief capacity to protect system integrity and comply with local mechanical codes. Its corrosion-resistant construction and stainless steel spring ensure long-term performance in demanding mechanical rooms.
