Review APOLLO New In Box Valves Threaded End Thermal Expansion Relief Valve 3/4 Inch

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:

Pros:

1. Durable Construction: Apollo 78RV-117-125 TEV is made of brass, which is known for its strength and corrosion resistance. Brass is also an excellent material for high-temperature applications.

2. Reliable Performance: This TEV is designed to open automatically when the temperature and pressure exceed safe levels, preventing damage to the system.

3. Easy Installation: The box design of the Apollo 78RV-117-125 TEV makes it easier to install than some other models, as it requires less piping and fitting.

4. Adjustable: The TEV comes with an adjustable spring, allowing users to set the relief pressure to their specific system requirements.

5. Safety Feature: The TEV provides an essential safety feature for heating systems, preventing damage caused by thermal expansion and potential system failure.

Cons:

1. Cost: The Apollo 78RV-117-125 TEV may be more expensive than some other relief valve models due to its brass construction and additional features.

2. Size: This TEV is larger than some other models, which may require more space for installation.

3. Maintenance: Like all relief valves, the Apollo 78RV-117-125 TEV requires regular maintenance to ensure proper functioning. This includes checking for leaks and testing the valve function periodically.

Conclusion:

The Apollo 78RV-117-125 box valve with an end thermal expansion relief valve is a reliable and durable option for heating systems. Its brass construction, adjustable spring, and easy installation make it a preferred choice for many users. However, its cost and size may be a consideration for some. Ultimately, the decision to purchase this model depends on the specific needs and budget of the user.

Recommendation:

If the user is looking for a reliable and durable relief valve with easy installation and adjustability, the Apollo 78RV-117-125 box valve with an end thermal expansion relief valve is an excellent choice. However, if cost is a concern, users may want to consider alternative models made of less expensive materials or with simpler designs. Additionally, regular maintenance is essential to ensure the longevity and proper functioning of the valve.

Details:

It is designed for threaded connections and suitable use in heating, cooling, air systems. The product is a new in box Apollo Valves threaded end thermal expansion relief valve, model EXVT 125T 3/4LF, made of brass. This valve offers smart home protocol for threaded ends and was manufactured in the year 2022, ensuring compatibility with modern systems requirements.
