The Apollo 78RV-117-125 is a high-performance, 3/4 inch thermal expansion relief valve designed for use in heating systems. This valve, manufactured by Apollo Valve, is engineered to provide reliable protection against excessive pressure build-up caused by thermal expansion of fluids.
The body of the Apollo 78RV-117-125 is constructed from durable brass, ensuring resistance to corrosion and longevity. It is equipped with a 3/4 inch NPT thread connection, making it compatible with standard pipe sizes. The valve's temperature range is designed to accommodate various heating applications, with a minimum recommended temperature of 60 F (15.6 C) and a maximum recommended temperature of 257 F (125 C).
The valve's internal components include a sensing bulb, spring, and disc assembly. The sensing bulb is filled with a temperature-sensitive fluid that expands when heated, which in turn pushes against the diaphragm and activates the valve. Once the preset temperature is reached, the valve opens to release excess pressure, preventing potential damage to the system.
The Apollo 78RV-117-125 is designed to meet the ASME Boiler and Pressure Vessel Code (Section I, Power Boilers; Section IV, Heating Boilers) and the American Society of Mechanical Engineers (ASME) B16.34 standard, ensuring compliance with rigorous safety and quality standards. The valve comes with a factory-set pressure relief rating of 150 psi (10.3 bar), but it can be customized with various pressure settings upon request.
Additionally, the valve features a test port for easy pressure testing, allowing users to ensure the valve is functioning correctly and providing optimal protection for their heating systems. The valve also comes with a temperature-sensitive spring that automatically resets the valve once the excess pressure has been released and the system has cooled down.
In summary, the Apollo 78RV-117-125 is a reliable and robust thermal expansion relief valve designed for use in heating systems. Its brass construction, 3/4 inch NPT thread connection, and compatibility with a wide temperature range make it a versatile and effective solution for preventing excessive pressure build-up and protecting against potential damage to heating systems.
Apollo 78RV-117-125 box valves with end thermal expansion relief valves (TEV) are commonly used in heating systems to prevent damage caused by excessive pressure due to thermal expansion. Here are some pros and cons of buying this specific model:
