Structural features

The main structural characteristics of flange lift check valve: 1, exquisite selection, in line with domestic and foreign standards, with comprehensive high quality of materials. 2, flange lift check valve seal pair is mateched advanced and reasonable, the disc and seat sealing surface adopt iron-based alloy or stellite cobalt-based hard alloy build up welding, with wear-resistance, high temperature resistance, corrosive resistance, good anti-abrasion performance, long service life. 3, flange lift check valve is designed and manufactured according to GB/T12235 national standard. 4, it can be used with a variety of flange standards and flange sealing types, to meet the various engineering needs and user requirements. 5, full range of body materials, gaskets can be matched reasonably based on the actual working conditions or the user requests. It can be applied to all kinds of pressure, temperature and medium conditions. According to user requirements, we can design and manufacture check valves with different structural forms and connection forms, for supporting the use of various equipment. Flange lift check valve is used in the pipelines of oil, chemical, fire station and other working conditions that the nominal pressure is PN1.6 ~ 6.4MPa, working temperature is -29 ~ 550 ℃. Applicable medium: water, oil, steam and so on.
