2507 duplex steel three eccentric butterfly valve, three eccentric butterfly valve, 2507 butterfly valve

2507 duplex steel three eccentric butterfly valve, seawater resistant, material: 2507 duplex steel, sealed PTFE, 2507 duplex steel PRE value 40, flange connection, pressure: 1.0MPA-6.4MPA, diameter DN50-DN1200.

Dual phase steel three eccentric butterfly valve, by the valve body, butterfly plate, stem, sealing ring and other main components, valve structure using three-dimensional eccentric principle design, reliable sealing, can meet all levels of standards, at the same time flow characteristics are good, with adjustment function

Three eccentric butterfly valve, through the elasticity of the sealing ring on the butterfly plate to achieve sealing zero leakage, the contact surface of the sealing ring and the valve seat is oblique conical, the contact Angle between the butterfly plate sealing ring and the valve body seat produces a slight "wedge effect", so that the sealing ring occurs soft and radial compression. Due to the uniform contact between the seat and the sealing ring and the flexibility of the sealing ring, the load on the seat is uniform, so that the tightest cut is achieved with the minimum torque.

2507 double phase steel three eccentric butterfly valve due to its excellent corrosion resistance and mechanical properties, suitable for a variety of harsh conditions. The following are the main application scenarios: Seawater desalination: suitable for the treatment of seawater, acid and alkali solvents, high concentration chloride ion wastewater and other corrosive media, such as seawater desalination project continuous operation for 3 years without corrosion leakage. Petrochemical industry: stable performance in high temperature and high pressure environment, such as Sinopec Zhenhai Refining & Chemical 3 million tons/year hydrocracking plant project, suitable for temperature 450℃, pressure 12MPa working condition. New energy field: including hydrogen energy industrial park project, electric duplex steel butterfly valve adopts anti-hydrogen embrittle duplex steel and metal hard seal + flexible graphite reinforced structure, suitable for 35MPa high-pressure hydrogen energy scenario, to achieve continuous 18 months of high pressure without leakage. Municipal water: It is used to deal with strong corrosion conditions such as chlorine, sulfur and high salt, and meet the core needs of fluid control safety and stability in different engineering scenarios. Supercritical power generation: excellent performance under ultra-high temperature and ultra-high pressure conditions, such as Shanghai supercritical power station 566℃ main steam system, continuous operation for 24 months without erosion, no stagnation
