Overfill Prevention Valves

Overfill Prevention Valves and Limit Switch

For safety during tank filling

The filling safety device prevents overfilling of storage tanks and bunker tanks when they are filled by tank trucks with petrol, diesel and heating oils. It comprises an overfill prevention sensor inside the tank and a repeater with an actuator inside the tank truck.

The QSS-/ASS connection valve is part of a security system. Here the hose connection to the tanker is checked and the mixing of products caused by incorrect connection during the tank filling is prevented.
