Conbraco 18C-512-8-150 Valve

The Conbraco 18C-512-8-150 is a high-capacity commercial temperature and pressure relief valve designed for the rigorous demands of large-scale hot water storage tanks and boiler systems. Featuring a 3/4 inch FNPT inlet and a 3/4 inch FNPT outlet, this bronze-bodied safety device is engineered to provide critical overpressure protection. It is factory set to discharge at 150 PSI and 210°F, boasting an impressive ASME Section IV certified capacity of 1,912,000 BTU/hr. The 8-inch extended thermal probe is coated to resist mineral buildup and corrosion, ensuring accurate temperature sensing deep within the water column.

• Maximum Discharge Capacity: Rated for up to 1,912,000 BTU/hr to support high-output commercial water heaters.
• Corrosion Resistance: Features a bronze body construction and a coated element for long-term reliability in harsh water conditions.
• Standardized Fit: 3/4" female NPT connections allow for straightforward integration into existing manifold configurations.
• Code Compliance: Meets ASME Section IV and ANSI Z21.22 standards for professional-grade safety installations.

• Is the probe length measured from the body? Yes, the 8-inch probe length ensures the sensing element reaches into the tank's optimal heat zone for faster thermal response.
• Can this be used on steam boilers? This specific model is designed for hot water service. Always verify your system's medium (water vs. steam) before selecting a relief valve.
• What causes this valve to drip? Minor dripping often indicates thermal expansion within a closed system rather than a valve defect. Installing an expansion tank is usually the recommended fix.
