Overfill Prevention Valve for Plastic Tanks
The overfill prevention valve is a unique device which replaces the standard 2” BSP fill point on both domestic and commercial fuel storage tanks.
Unlike an overfill warning alarm which simply warns the delivery driver to stop filling, the FillStop OFPV actually prevents the tank from being overfilled.
Using a unique design, the valve allows fuel to pass until the maximum level is reached at which point it isolates the supply of fuel into the tank ensuring that it is not overfilled.
This version is for plastic tanks. If you have a steel tank, please see this version.
The tank ullage is reduced by 120mm (approx.) from the fixing point
