Advantages of Overflow Valve
Supports Regulatory Compliance
Properly installed valves help homeowners meet local and federal regulations related to oil storage. These systems often include a check valve and flow measurement tools to verify performance. It goes without saying, but following regulatory compliance reduces the risk of fines and legal issues.
Reduces Equipment Wear
Avoiding overfills reduces pressure on components like the pump and nozzle during fuel transfer, which can potentially extend the life of storage tank equipment and limit the need for repairs in the long run. Of course, consistent maintenance keeps the tank operating efficiently year-round, but having an overflow valve installed can also help minimize issues.
Improves Safety During Fuel Deliveries
By stopping excess oil from entering the tank, overflow prevention valves create a safer delivery process. Tank trucks connected via pipe and siphon systems rely on valves to control the flow, and a safe delivery limits the risk of an emergency situation caused by fuel spray or overflow.
Better Leak Detection
Valves support leak detection by helping to maintain steady fluid levels during fuel transfers. Sudden drops or inconsistencies can indicate a leak or a faulty sensor in the tank, prompting homeowners to take action. Early detection plays a vital role in protecting nearby soil and groundwater, as well as addressing other problems that a tank leak can create.
Optimizes Fuel Flow and Calibration
An accurate calibration of the valve allows for better control of fluid transfer rates and flow measurement. The valve can be paired with sensors to monitor real-time conditions inside the tank. With an overflow prevention valve in place, it becomes easier to maintain consistent oil levels and promote efficient fuel usage.
Protects the Surrounding Property
Overflow valves help prevent liquid from escaping the tank and damaging surrounding areas, such as basements or crawl spaces, as leaked oil can corrode nearby equipment and pose a serious fire hazard. Preventing such leaks protects your property and gives you peace of mind knowing there’s protection in place.
Prevents Hazardous Backflow
In some systems, an overflow prevention valve combined with a check valve can prevent hazardous backflow into the tank. This protection safeguards the engine and connected heating systems from contamination. Moreover, backflow prevention also keeps the storage tank and pipes clean and functional.
Installation of Overflow Valve

Designed for Underground Storage Tanks:
The valve's design takes into account the unique conditions and requirements of underground storage tanks. These tanks are typically used to store large quantities of liquids, such as fuel or water, and are buried beneath the ground for safety and space-saving purposes. The valve's features, such as the vertical floating body design and the spring-loaded two-stop damper, are optimized for use in these environments, where access to the valve can be limited and the effects of gravity and pressure can be significant.

Gravity Unloading Only:
The valve is specifically intended for gravity unloading, which means it relies on the natural force of gravity to drain the liquid from the tank. This is a common method of unloading liquids from underground storage tanks, as it requires no additional energy source and can be done safely and efficiently. Attempting to use the valve for pressurized unloading or in any other manner not intended by the manufacturer can compromise its effectiveness and lead to dangerous situations.

Dangers of Misuse:
Using the valve in a ground tank or for any application other than gravity unloading can have severe consequences. Ground tanks are subject to different pressures, temperatures, and other environmental factors than underground tanks, which can affect the valve's performance. Additionally, attempting to use the valve for pressurized unloading can cause it to malfunction or fail, potentially leading to leaks, spills, or even explosions. These hazards not only pose a threat to the environment but also to the safety of personnel working in the area.
