Currently, the control of polluting gas emissions is of great importance for the industrial segment, mainly due to two factors: reduction of atmospheric pollution and the financial costs generated by the reduction of evaporation losses.

The above factors can be classified not only as market requirements, but also, in the case of reducing air pollution, as a requirement of International Standards, such as ISO 14000.

CONAMA and several state agencies are demanding control over the emission of pollutants. The use of valves or similar equipment to vent fuel tanks is essential to reduce environmental contamination, as attested by environmental bodies that confirm the reduction in atmospheric emissions.
