Featuring a \u003cstrong\u003e3\/4 inch FNPT inlet and outlet\u003c\/strong\u003e, this valve is factory set to \u003cstrong\u003e75 PSI\u003c\/strong\u003e to ensure reliable system safety and over-pressure protection. With a high flow capacity of \u003cstrong\u003e972,000 BTU\/hr\u003c\/strong\u003e and a maximum temperature rating of \u003cstrong\u003e250°F\u003c\/strong\u003e, this \u003cstrong\u003ebrass relief valve\u003c\/strong\u003e is built to withstand the rigors of commercial and residential boiler applications. The \u003cstrong\u003eApollo 10-400 series\u003c\/strong\u003e design utilizes a high-capacity \"soft seat\" to ensure positive shut-off after over-pressure events, reducing the risk of persistent seat leakage. Contractors typically utilize this model for \u003cstrong\u003eboiler pressure regulation\u003c\/strong\u003e where an ASME-certified safety device is required to meet local mechanical codes. The durable bronze body and corrosion-resistant hardware provide long-term reliability in demanding hydronic environments without the performance degradation seen in lower-grade components.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits for Hydronic Systems:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh BTU Rating:\u003c\/strong\u003e Rated for up to \u003cstrong\u003e972,000 BTU capacity\u003c\/strong\u003e, making it suitable for larger boiler configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASME Section IV Certified:\u003c\/strong\u003e Meets strict \u003cstrong\u003eASME safety relief valve\u003c\/strong\u003e standards for hot water heating boilers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Brass Construction:\u003c\/strong\u003e High-quality \u003cstrong\u003ebrass hot water pressure relief valve\u003c\/strong\u003e body resists corrosion and mineral buildup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Threading:\u003c\/strong\u003e Dual \u003cstrong\u003e3\/4\" female NPT\u003c\/strong\u003e connections allow for straightforward field installation and replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Stability:\u003c\/strong\u003e Engineered to maintain seal integrity at temperatures reaching the \u003cstrong\u003e250 degree F maximum\u003c\/strong\u003e limit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eFrequently Asked Questions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between a 75 PSI relief valve and a standard 30 PSI boiler valve?\u003c\/strong\u003e\u003cbr\u003e\nThe \u003cstrong\u003eConbraco 10-418-15\u003c\/strong\u003e is specifically set at \u003cstrong\u003e75 PSI\u003c\/strong\u003e for systems that operate at higher static pressures or in multi-story buildings where a standard 30 PSI valve would cause nuisance tripping.
