Conbraco Products 10-618-05 Valve

The Conbraco Products 10-618-05 is a high-capacity hot water boiler pressure relief valve designed for large-scale commercial and industrial hydronic heating systems. Engineered with a 2" Female NPT inlet and a 2-1/2" Female NPT outlet, this ASME Section IV certified valve is factory set at 30 PSI to prevent over-pressurization in high-output boilers. With a verified steam discharge capacity of 6,091,000 BTU/hr, it provides essential protection for large BTU systems where safety and reliable blowdown are non-negotiable. The bronze body construction and EPDM-to-metal seating ensure long-term durability and leak-free operation under constant thermal cycling. This Apollo 10-600 series valve features a top-guided design and a high-surface-area discharge path to maximize flow rates during critical overpressure events. For field technicians, the 10-618-05 is a standard heavy duty boiler safety valve replacement that ensures HVAC system compliance with local mechanical codes and ASME standards.
