According to national standards (fire protection design of petrochemical enterprise) ( GB50160-92 ) Provisions: Store A, B liquid fixed roof tanks, flame arrester should be located and Hu suction valve.

? Visible Hu suction valve, flame arrester tank is not lack of safety facilities.

? It can not only maintain the pressure balance tank to ensure the tank from damage when the overpressure or vacuum, and can reduce evaporation and loss of the tank medium.

? I produced Hu suction valve, with a compact, ventilation volume, leakage, good sealing performance characteristics.

? Recently we developed an internationally advanced level of explosion-proof flame arrester Hu suction valve ( HXF-IZ Type), flame arrester located Hu suction valve suction port, the complete elimination of ignition sources to enter Hu suction valve housing having a small size, light weight, maintenance, cleaning, easy replacement
