To protect against costly tank over-flows and comply with increasing regulations, today’s storage tank owners must install reliable overfill prevention valves.

Core’s FillGuard Overfill Prevention Valve (OPV) is the industry’s most effective solution. This maintenance-free system features advanced, positive shutoff technology that brings the delivery of liquid to a tank to a smooth stop when the liquid level reaches desired capacity.

The FillGuard OPV prevents spills while providing faster filling than existing slow "fill limiter" designs, resulting in improved productivity. Featuring a positive shutoff design, it carries the UL listing for Positive Shutoff Overfill Protection Device for Aboveground Tanks and Flammable Liquids. The valve provides gradual shutoff at predetermined levels to prevent stress and line shock.
