We can say that it mainly regulates gas. Breathing valve is the main safety equipment installed on fixed roof storage tanks such as crude oil, gasoline, kerosene, light diesel, aromatics, etc. It plays the role of evaporation loss and protects the storage tank from damage in the event of overpressure or vacuum. The all-season (fireproof) breathing valve produced by Yantai Haifei Company (www.ythfsy.com) has the advantages of reasonable structure, large ventilation volume, good sealing performance, small leakage and corrosion resistance.
