According to the provisions of China's "Fire Protection Code for Petrochemical Design" : "The fixed roof tank of class A and B liquids shall be equipped with a flame arrester and a breathing valve." The type of breathing valve products in China is single, but also can not meet the needs of all kinds of petrochemical tank farms, our company developed API 2000 series breathing valve, emergency relief valve products. The product has the advantages of complete specifications, large ventilation, good sealing performance and so on. The product types are air exhaust breathing valve, breathing valve with nozzle, single call valve, single suction valve, etc. According to the different pressure can be divided into gravity load type, spring load type. All specifications of the breathing valve can be used with the flame arrester.

Conventional valves are suitable for -29 ° C ~+120 ° C, if beyond this range, please specify when ordering.
Flame arrester refers to the safety protection equipment that prevents the flame from spreading and spreading in the pipeline. Generally installed in the pipeline conveying combustible gas, or on the ventilated tank, to prevent the transmission of flame (deflagration or detonation) through the device, consisting of a fire retardant core, flame arrester shell and accessories. Flame arresters are also commonly used in pipelines carrying flammable gases.
