Overfill Valves

This 3" Overfill Prevention Valve is designed to be used with above ground storage tanks to prevent overfilling. The valve physically closes the inlet to the tank when the fuel level inside reaches it's maximum during a fuel delivery. This prevents damage to the tank, and environment as well as the costs associated with cleaning spilt fuel.

The thread is 3" BSPP and can be screwed into a 3" BSPP Female Socket. Thanks to it's design, this valve only takes 75mm of tank space so doesn't effect tank capacity as much as other brands.

The valve physically closes the inlet to the tank when the fuel level inside reaches it's maximum during a fuel delivery. This prevents damage to the tank, and environment as well as the costs associated with cleaning spilt fuel.

The thread is 2" BSPP and can be screwed into a 2" BSPP Female Socket. Thanks to it's design, this valve only takes 59mm of tank space so doesn't effect tank capacity as much as other brands.

The Filstop 2" Overfill Prevention Valve is designed to act as the fill point for both metal and plastic tanks. The valve physically closes the inlet to the tank when the fuel level inside reaches it's maximum during a fuel delivery. This prevents damage to the tank, and environment as well as the costs associated with cleaning spilt fuel.

The steel tank version screws straight into the 2" BSP Inlet, whereas the plastic version requires a hole to be cut into the top of the tank for fixing via locknut.

The Cleanfill 2" Overfill Prevention Valve from Lafon can be fitted to a tank as a piece of safety and environmental protection equipment. This overfill protection device can be used on fuel and diesel storage tanks that are filled by gravity flow or a pressure pump system. When the tank is full, the valve will close preventing any further fluid from being dispensed into the tank. There is also a version available to be used on AdBlue™ storage tanks, a fluid which is known as DEF in America and other countries.

The SpillStop 2” Overfill Prevention Valve protects both the environment and the individual from the effects of fuel spillage. This overfill protection device is suitable for use on both fuel and diesel storage tanks, which may have a pumping or gravity feed system. Once the tank has reached its maximum fuel capacity, this valve will close to prevent any additional fuel from being delivered, thus preventing overfilling. A version of this can be supplied specifically for use on plastic tanks.
