A Flow Control Valve, a Level Sensor, and a Pilot Line make up a Banlaw FillSafeTMZero system. When a Level Sensor detects that the tank is full, the Flow Control Valve closes, thereby stopping the flow of diesel into the tank.

FillSafe Zero's design is extremely adaptable. Customers can mix and combine Flow Control Valve and Level Sensor choices to meet their individual needs, such as several tanks on the same machine, remote installation, integrated tank venting, and cost savings.
