  • Product description
    Oxygen specific cut-off valve is made of silicon brass or stainless steel casting material, with high mechanical strength, wear resistance, good safety and so on. Used in the oxygen pipeline, with the best anti explosion flame retardant performance, eliminating the safety factors on the oxygen pipeline. The oxygen valve is forced to seal the valve, so when the valve is closed, the valve must be applied to the valve pressure to force the sealing surface does not leak. Oxygen valve is a kind of special valve of the oxygen pipe network. Stood in the city of liquefied petroleum gas reserves, the oxygen valve is also used in refinery, petroleum chemical plant, petrochemical plant of liquefied gas system, as a control device for opening and closing the closure of media.
