Water Retention Valves

The water entry solution in fuel tanks is as simple as installing a water retention valve from Rafibra in the fuel tank suction lines.

The water valve is a device that completely solves the common problem which is caused when water accidentally filters inside the tank or container. These small ingresses of water inside a fuel tank can be caused by intense rain, among other reasons, and cause a huge inconvenience since the complexity of the installations hinders its detection and removal from the fuel tanks and containers.
