Oxygen is the factory with a point and each valve box Iron and Steel Design Institute of Metallurgical Ministry jointly developed the patented product. 92 years of professional experts from the National Institute of Iron and Steel Design major gas identification, good performance. This product has a voltage regulator, voltage regulators, flame arrester, filters, etc., widely used in metallurgy, chemical industry, shipbuilding, machinery and other industries need oxygen operations departments (such as welding, flame cutting, scarfing and other users point). Production of the product according to Pressure Vessel Code Operation (GB150) 

      OX/B-1-3 type oxygen valve box with the point of the pressure and flow of oxygen can be fulfilled by adjusting the valve; air reservoir prior to export, to ensure that users point pressure stability; valve in front of the filter for filtering in addition to the oxygen impurities in the solid state, to ensure the smooth operation of the terminal equipment. Peep valve box set front window can directly observe and understand the changes in system pressure situation.
