Double Flanged Stainless Steel Butterfly Valve
The double flanged stainless steel butterfly valve adopts a triple-eccentric hard-sealing structure, which is mainly made of stainless steel materials and has strong corrosion resistance. It is mostly used in industrial pipelines to regulate flow and cut off fluids. At present, it is widely applied in industries such as petrochemical, electric power, metallurgy, drainage, and municipal construction, playing an important role in our lives.
The double-flange butterfly valve is composed of two flanged connections, with a rotatable butterfly valve installed between them. The main function of the double-flange butterfly valve is to control the fluid in the pipeline, keeping it flowing stably within a certain range.

Main features of three eccentric stainless steel butterfly valves.
Due to the use of three eccentric structure, reliable sealing performance, to ensure that the butterfly plate does not touch the sealing seat when opening, eliminating the uneven load on the sealing seat, prolonging the service life, to ensure reliable sealing performance, high temperature resistance, wear resistance, corrosion resistance and other advantages.
The applications of stainless steel butterfly valves.
Stainless steel butterfly valves adopt a three eccentric multi-level metal hard seal structure and are widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction where the medium temperature is ≤ 425 ℃. They are used for regulating flow and carrying and breaking fluids. The valve adopts a three eccentric structure, and the valve seat and disc sealing surface are made of different hardness and stainless steel, which has good corrosion resistance and long service life.
Are stainless steel valves worth it?
Yes, stainless steel valves are worth it. They offer excellent corrosion resistance, durability, and high-temperature/pressure tolerance, making them suitable for harsh environments in industries like chemical, marine, and food processing. Though often more expensive upfront, their long lifespan and low maintenance costs provide long-term value.
Which is better brass or stainless steel valves?
The choice between brass and stainless steel valves depends on the application:
Brass valves are cheaper, easier to machine, and suitable for low-pressure, non-corrosive environments (e.g., residential plumbing).
Stainless steel valves offer superior corrosion resistance, strength, and durability for high-pressure, harsh conditions (e.g., industrial, marine, or chemical use).
Conclusion: Stainless steel is better for demanding, corrosive applications, while brass is preferable for simple, low-stress needs.
