Flange hard seal. Compared with ordinary soft seal floating ball valve, the difference is that the latter is a soft seal seat, while the former ball and seat are hardened by a special process, hardening in many ways, such as: The ball and the seat have integral nitriding, flame spraying, surfacing, etc. (not limited to this), the choice of hardening mode depends on the working medium or user requirements to determine; Metal hard sealed floating ball valve is widely used in natural gas, oil products, chemical industry, metallurgy, paper making, electric power, mining, printing and dyeing, biopharmaceutical, daily chemical industry, food and beverage, water treatment and air treatment and other industries, especially suitable for high temperature and media containing various dust and solid particles.
Flange hard seal ball valve product features:
1, universal products, mature structure, compact, simple, easy maintenance.
2, the ball is sprayed with ultra-British speed abrasion-resistant alloy powder material, and the seat is surfacing welded Stellite carbide and sprayed with other ultra-wear-resistant alloy materials.
3, sealing surface fine grinding, sealing reliable and guaranteed.
4, full flow channel design, small flow resistance, large flow capacity.
5, the valve stem anti-fly design, safe and reliable, can be designed according to the requirements of anti-static function.
Gb flange type hard sealed ball valve in oil, natural gas, coal and ore mining, refining and processing and pipeline transportation system; In the production of chemical products, pharmaceuticals and food; In hydroelectric, thermal and nuclear power generation systems; In water supply and drainage, heat supply, and gas supply systems of urban and industrial enterprises; In the drainage and irrigation system of farmland; It has been widely used in the gold production system, and is an important mechanical product closely related to production construction, national defense construction and people's life. Ball valve closed in all kinds of pipeline systems are used to cut off or connect the medium flow, so that the medium is transmitted to each designated point in accordance with the predetermined procedure.
