Conbraco Industries 18C-522-8-125 Valve
The Conbraco 18C-522-8-125 is a high-capacity Temperature and Pressure Relief Valve designed for heavy-duty protection of commercial water heaters and storage tanks. This Apollo Valves 18C Series T&P valve is factory set at a 125 PSI relief pressure and a 210°F temperature limit. Featuring a 1" FNPT inlet and outlet, it delivers a massive 3,070,000 BTU/hr steam relief capacity, ensuring safety in high-demand potable water systems. The 8-inch probe provides accurate thermal sensing deep within the tank, preventing dangerous overheating. Constructed with a bronze body and stainless steel springs, this 18C-522-8-125 model is the standard for contractors requiring an ASME Section IV certified safety relief solution that manages both thermal expansion and over-pressurization in large-scale domestic hot water applications.
Key Benefits for Contactors:
- Maximum System Safety: Verified 3,070,000 BTU capacity meets the needs of large commercial boilers and high-input water heaters.
- Precise Thermal Sensing: The 8" extended probe ensures the element is submerged in the hottest water for rapid response.
- Standardized Fit: 1-inch Female NPT connections allow for straightforward integration into existing hydronic or domestic water piping.
- Industrial Durability: Robust bronze construction resists corrosion and scaling in aggressive water conditions.
- Code Compliance: Designed and certified to meet ASME and ANSI Z21.22 requirements for T&P relief valves.
Common Technical Questions:
What is the difference between this and a standard residential T&P valve?
The 18C-522-8-125 features a significantly larger 1" port and a much higher discharge capacity (over 3 million BTU/hr) compared to standard 3/4" residential valves, which typically handle around 100,000 BTU/hr.
Can this valve be installed in any orientation?
For proper operation, the valve should be installed so that the probe is in the top 6 inches of the tank where the water is hottest, typically in a vertical or horizontal position as specified by local plumbing codes.
Does the 8-inch probe length include the threads?
The probe length is measured from the end of the thermal element to the bottom of the valve body threads to ensure it extends sufficiently into the tank shell.
