The Basics

An important part of the Banlaw FillSafe Zero system is the Pilot Line.

The key role of the Pilot Line is to provide a ‘signal’ link between the Flow Control Valve and the Level Sensor. The Pilot Line provides the back pressure signal that the Level Sensor has made contact with diesel. This signal causes the Flow Control Valve to close and prevent additional fuel from entering the tank.

The Banlaw FillSafe Zero system may incorporate either an External or Internal Pilot Line depending on the choice of Flow Control Valve used.

Banlaw FillSafe overfill protection systems ensure safe, high-speed, reliable diesel refuelling with zero pressure build-up in the tank, ensuring cost-efficient installs.  Banlaw manufactures both mechanical and electronic solutions for tank overfill protection, catering to storage tanks and diesel-powered machines of all sizes. All products are designed to protect valuable machine assets, providing the widest choice of zero tank pressure overfill protection systems available on the market.

A Banlaw FillSafe Zero system consists of a:

• Flow Control Valve,
• Level Sensor
• Pilot Line.

The Flow Control Valve closes when a Level Sensor detects that the tank is full, stopping the flow of diesel from entering the tank. The Banlaw FillSafe Zero Range is configurable to allow a choice of either an internal or external pilot line.

Valve variants are available that fit directly into a 2” shell, refuel at up to 1000lpm, include a Dry Break Receiver, or are provided with process connections for in-line deployment.
