The DN2600 eccentric butterfly valve is a high-performance large-diameter control valve specially designed for ultra-large pipeline systems, integrating excellent sealing performance, structural stability and energy-saving advantages. It adopts an eccentric structural design (eccentric shaft + eccentric disc), which fundamentally solves the problem of friction between the disc and the sealing ring during the opening and closing process of traditional butterfly valves, greatly reducing wear and tear, and ensuring long-term stable operation under high-pressure and large-flow working conditions.

The valve body is made of high-quality ductile iron, stainless steel or carbon steel, which is processed by precision casting and heat treatment technology, ensuring excellent mechanical properties, high tensile strength, good toughness and strong corrosion resistance, and can adapt to various harsh working environments such as outdoor low temperature, high humidity, and corrosive medium erosion. The sealing structure adopts high-performance EPDM, NBR or PTFE sealing ring, combined with precise machining of the valve seat and disc, to achieve zero leakage, effectively preventing medium loss, environmental pollution and safety hazards caused by medium leakage.

Advantages of DN2600 Eccentric Butterfly Valve

1. Excellent Sealing Performance & Wear Resistance

Adopting a unique eccentric structural design, the disc and the sealing ring are completely separated during the opening and closing process, avoiding friction and wear, and ensuring the integrity of the sealing ring for a long time. High-quality EPDM, NBR or PTFE sealing rings are selected, combined with precision machining technology of the valve seat and disc, to achieve strict zero leakage, which can effectively prevent medium leakage, avoid environmental pollution, economic losses and safety hazards, and is especially suitable for occasions with high sealing requirements such as large-diameter clean water transportation, gas transmission and chemical medium transmission.

2. Stable Eccentric Structure & Long Service Life

The valve adopts an integrated eccentric shaft and disc structure, with reasonable force distribution, strong structural stability, and can withstand the pressure impact and flow impact of DN2600 ultra-large-diameter pipeline systems.

3. Energy-saving & Convenient Installation & Transportation

The streamlined optimized design of the disc reduces the flow resistance coefficient of the valve, minimizes the energy consumption of the pipeline system during large-flow medium transportation, and achieves significant energy-saving effects, which is in line with the concept of green and energy-saving development.

4. Flexible Operation & Easy Maintenance

It supports multiple operation modes such as manual, gear-operated, pneumatic and motorized, which can meet the needs of different working conditions of DN2600 ultra-large-diameter pipeline systems, such as on-site manual operation, gear-assisted operation for large torque, pneumatic quick control, and motorized intelligent remote control.

Applicable Working Conditions of DN2600 Eccentric Butterfly Valve

The DN2600 eccentric butterfly valve is mainly suitable for DN2600 ultra-large-diameter pipeline systems that require good sealing performance, small flow resistance, stable operation, convenient installation and maintenance, and is widely used in various large-scale industrial, municipal and water conservancy projects, providing reliable flow control and cut-off functions for ultra-large pipeline systems.

For example:

Large-scale Water Plant and Sewage Treatment Plant

In the ultra-large-diameter water supply and drainage system, it is used to control the flow of clean water, raw water, sewage and sludge in DN2600 pipelines. The zero leakage performance prevents secondary pollution of water quality, and the small flow resistance is suitable for large-flow water transportation, which improves the efficiency of the water treatment system.

Municipal Ultra-large Diameter Pipeline System

Applied to municipal water supply, drainage, heating and gas main pipelines with DN2600 specifications.

Petrochemical and Thermal Power Plant

Used to control the flow of heavy oil, light oil, chemical solvents, circulating water and flue gas in DN2600 large-diameter pipelines of petrochemical plants and thermal power plants.

Large-scale Water Conservancy Project and Metallurgical Industry

In large-scale water conservancy projects (such as reservoirs, diversion projects) and metallurgical industry, it is used to control the water flow, cooling water and smelting medium in DN2600 ultra-large-diameter pipelines.
