Product details:

The DN700 stainless steel triple eccentric hard seal butterfly valve is a large-caliber industrial valve specially designed for DN700 pipeline systems. Its core advantages lie in the "triple eccentric" structural design and high-quality stainless steel hard seal material. As a large-diameter valve, it is optimized for large-flow medium transportation, and compared with traditional soft-sealed butterfly valves and small-caliber butterfly valves, its sealing surface is made of stainless steel (SS304/SS316/SS316L) or carbide, which ensures stable operation under harsh working conditions such as high temperature, high pressure, strong corrosion and large flow.

Its structural design is fully adapted to the characteristics of DN700 large-diameter pipelines, which can effectively control the on-off and flow regulation of large-flow media, and maintain excellent sealing performance and operational stability even in extreme environments. It is especially suitable for occasions that require reliable sealing, large flow capacity and long-term stable operation, such as high-temperature steam pipelines in large power plants, large-diameter corrosive medium transportation pipelines, and municipal water supply main pipelines.

What are the characteristics and biggest advantages of DN700 stainless steel butterfly valve?

Here are its main features and biggest advantages:

Friction-free seal for large-diameter operation:
Thanks to the triple-eccentric design, the DN700 butterfly valve has almost no friction between the butterfly plate and the sealing surface when opening and closing, which solves the problem of easy wear of large-diameter valves during operation.

High temperature and high pressure resistance, suitable for large-flow:
For DN700 large-diameter pipelines, which often bear large medium pressure and flow, the hard-sealed structure can avoid seal failure caused by aging or deformation of soft-sealed materials, and ensure stable operation under harsh conditions such as high-temperature steam and high-pressure industrial water.

Strong corrosion resistance, adaptable to multiple media:
The main body and sealing surface of the DN700 butterfly valve are made of stainless steel materials, which have excellent corrosion resistance and can be used to transport corrosive media such as weak acids, alkalis, and salt solutions.

Long service life:
Even under frequent opening and closing operations of large-diameter pipelines, it can still maintain a long service life.

High sealing reliability and strong flow regulation capacity:
The triple eccentric design allows the sealing surfaces of the butterfly plate to automatically fit closely when closing, achieving a self-locking function, which ensures no leakage of medium even under large flow impact.

Application conditions of DN700 stainless steel triple eccentric hard seal butterfly valve
Due to its excellent sealing performance, high temperature resistance, corrosion resistance, long service life and large-flow adaptation capacity, the DN700 stainless steel triple eccentric hard seal butterfly valve is especially suitable for various large-diameter, extreme and harsh industrial conditions. Specific application conditions include but are not limited to:

>Corrosive medium transportation in large-diameter pipelines

>Municipal and water treatment large-flow occasions

>High-frequency opening and closing large-diameter pipeline systems

>Harsh hydraulic conditions with large flow and particles

The DN700 stainless steel triple-eccentric hard-seal butterfly valve, as a key equipment for large-diameter industrial pipelines, has become an indispensable part of modern industry with its unique structural design, excellent performance and strong adaptability. It solves many common problems of large-diameter valves such as easy wear, poor sealing and short service life, and shows excellent performance and reliability especially in complex working conditions of high temperature, high pressure, strong corrosion and large flow.
