5A dual-phase stainless steel butterfly valve, stainless steel butterfly valve

D343H 5A duplex stainless steel butterfly valve is a specially designed butterfly valve, mainly used to meet the requirements of specific industrial environments. Here is a detailed introduction about this type of butterfly valve:

Material and Design: The valve body and butterfly plate of D343H 5A duplex stainless steel butterfly valve are made of 2507 duplex steel. This material can not only resist the corrosion and wear of desulfurization slurry, but also protect other components from the corrosion of limestone (or lime slurry), making it suitable for desulfurization and denitrification projects.

Sealing Performance: This butterfly valve adopts a three-eccentric sealing structure. The valve seat and the butterfly plate have almost no wear, and it has a sealing function that gets tighter as it closes. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperatures and has a long service life.

Operating Characteristics: D343H 5A duplex stainless steel butterfly valve is flexible and easy to operate, and the opening and closing only require rotating the valve stem by 90°. It is not affected by the pressure of the medium, and the sealing performance is reliable. In addition, the butterfly valve is equipped with a sealing adjustment device. If the sealing performance decreases after long-term use, the butterfly plate sealing ring can be adjusted to approach the valve seat to restore the original sealing performance.

Application Fields: D343H hard-sealed butterfly valve has remarkable application effects in the petroleum, chemical, and drainage industries. It can improve the sealing performance and operational efficiency of equipment, reduce maintenance costs and labor intensity, and meet the requirements of complex working conditions.

Application fields

Chemical and Petroleum Industry: In these industries, stainless steel butterfly valves are commonly used in high-temperature, high-pressure, and high-sealingity situations, such as petroleum refining and chemical reactors. Their ability to withstand high temperatures and corrosion makes them an ideal choice in these industries.

Food and Pharmaceutical Industry: In these industries with strict material requirements, stainless steel butterfly valves are widely used due to their non-toxicity, odorlessness, corrosion resistance, ease of cleaning, and absence of dead corners.

Metallurgy and Water Treatment Industry: In these industries, stainless steel butterfly valves are often used to control the flow and pressure of fluid media, especially in sewage treatment plants and metallurgical factories where reliability is required.

Electricity and Municipal Engineering: In the electricity industry, stainless steel butterfly valves are commonly used in cooling water systems of power stations; in municipal engineering, they are often used in water supply and drainage systems and urban heating production pipelines.
