There are two kinds of power station valve standard forms, one is introduced according to ANSIB16.34 and JISL1E101 standard, the other one is according to the national standard JB3595 type. It follows the temperature pressure rating is the same, in some pipeline there is a kind of exchange relation. In the central part, the pressure of the non bonnet is adopted, which has good sealing performance under high temperature and high pressure condition. Self sealing ring there are two kinds of materials, one is low carbon steel, the other is a flexible graphite 316 wire (net). The sealing surface of the upper welding drill base hard alloy, the processed pure metal layer is larger than 3mm, with wear-resistant, high temperature resistance and corrosion resistance, abrasion resistance, long service life. Pipe ends welded structure, welding groove can be made according to user requirements or standards. Suitable for water, steam, oil, superheated steam pipeline of water, steam, oil and superheated steam in thermal power plant, petrochemical industry, metallurgy and other high temperature and high pressure.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
