Valve reasonable structure, excellent performance, attractive appearance, suitable for a wide range of pressure, mainly used to connect or disconnect piping in the media, with wear-resistant, high temperature, anti-abrasion performance, long life. Cut-off valve, welded valve, globe valve DC, DC-type welding valve high pressure valve DC-type welding, DC-type welding valve, high temperature and pressure valve

J65H high temperature and pressure globe valve from the valve body, valve cover, valve stem, valve and other components. For the work under the conditions of high temperature and pressure valve, the sealing surface of the working conditions in poor conditions, so the sealing surface of the high performance requirements. Over the years, the widespread use of domestic and foreign prices of precious cobalt chrome tungsten welding the valve sealing surface as the material. To reduce costs, solve problems and improve weld cracks when the valve sealing surface machining performance, you can try in recent years, China developed a series of submerged arc welding of high alloy bonded flux, flux, such as bond No. 137, because of its good performance, prices moderate. J65H Once the high temperature and pressure valve is turned on its valve seat and valve between the sealing surface is no longer in touch with the sealing surface so it's less mechanical wear, valve seat and valve seal is easier to repair or replace components no need to remove the valve from the pipeline to which the valves and pipes welded into one of the occasions is very applicable. Medium through the valve when the flow direction of such change.
