FILSTOP OVERFILL PREVENTION VALVE
Suitable for use on almost any plastic fuel oil tank incorporating an industry standard 2" BSP(M) Fill Point, Atkinson's GV4000 Overfill Prevention Valve is proven to prevent overfills during refueling.
In the event that the level of fuel inside the tank reaches a critical level, the valve automatically activates to prevent an overfill. The Atkinson GV4000 is proven to dramatically reduce the risk of an environmental pollution incident at fuel oil storage tank installations.
**Please note: If used with Flammable liquids, the GV4000 valve must be installed into a Fill tube running to the tank floor.
Universal- fits metal tanks as standard, or plastic tanks using optional fitting kit.
For thin viscosity liquid petroleum fuels, such as diesel and Kerosene.
All metal construction - Stainless Steel, Anodised Aluminium, Brass and Zinc plated Brass.
Each valve is individually tested.
