2205 duplex steel butterfly valve, 2205 duplex steel butterfly valve, 2205 butterfly valve

Hard seal duplex steel butterfly valve, metal seal, three eccentric structure, pressure: 1.0mp-6.4mpa, caliber DN50-DN2000. Connection: flange, clamp, butt welding, lug. Applicable medium: seawater, acid liquid, salt liquid, liquid containing chloride ions and other corrosive medium, often used in seawater desalination, chemical wastewater treatment, desulfurization, food, electronics, paper and other industries.

2205 hard seal double phase steel butterfly valve, reliable seal, can meet all levels of standards, at the same time flow characteristics are good, with adjustment function. The valve structure adopts the principle of three-dimensional eccentricity design, so that the butterfly plate in the process of opening and closing, the butterfly plate sealing surface along the 360 degree circumference of each point of the moment contact or detachment, no sliding friction, no clamping between the seat, with the more closed the sealing advantages, eliminate the uneven load between the sealing pair, greatly prolong the service life of the valve.

Double stem design, anti blow out

Valve stem and butterfly plate, valve stem and drive, all adopt splinted connection structure, uniform force, easy disassembly and assembly, reduce the long-term maintenance cost of the product.

Lower valve stem fixed shaft structure, better rigidity, can shorten the valve stem inserted into the butterfly plate connection, so that the channel flow resistance is smaller.

The upper valve stem has no pin to prevent blowout structure. The design structure of the double valve stem solves the problem of inconsistent expansion between the valve stem and the butterfly plate and the valve body caused by thermal expansion.

Anti-lock, dustproof, anti-crystallization

Self-lubricating bushing design, to a greater extent to solve the valve stem lock problem, the upper and lower bearing dustproof structure, add spiral groove anti-crystallization structure.

The dynamic load packing machine with disc spring can automatically compensate the loss of packing and prevent the leakage of medium.

The 2205 hard seal duplex steel butterfly valve is widely used in many industrial fields due to its excellent corrosion resistance, high strength and durability, enhanced wear resistance, and accurate flow control. Specific application fields include: metallurgy, electric power, petrochemical, water supply and drainage and municipal construction: used in industrial pipelines with medium temperature ≤425℃, used for regulating flow and carrying and breaking flow. Chlor-alkali industry, soda ash industry, pharmaceutical industry, chemical fertilizer industry, fine industry, textile fiber synthesis and bleaching and dyeing industry: mainly used for high temperature alkali, sulfuric acid, fluoric acid, hydrochloric acid, phosphoric acid and other media control. Desulfurization of seawater and power plants: 2205 duplex steel butterfly valve is often used in these special environments. Chemical processing, oil and gas, petrochemical, power generation, water treatment: suitable for all kinds of corrosive, non-corrosive fluid media on the pipeline, used to regulate and cut off the flow of the medium. Shipbuilding industry: It is suitable for liquid control and flow regulation of all kinds of ships, including merchant ships, tankers, Marine generator sets, etc. 4. Wastewater treatment and water treatment: Used for liquid treatment and flow control in wastewater treatment plants, water treatment plants and industrial water systems.
