Triple Eccentric Butterfly Valveerfly valve has been born in the industry for more than 50 years, which has been in continuous development. With the continuous improvement of Triple Eccentric Butterfly Valveerfly valve, Triple Eccentric Butterfly Valveerfly valve has been applied to many industries. Do you really know about the three eccentric butterfly valve?
As the name suggests, three separate offsets are designed to be valves. Three eccentricity means:

1) the center line of the disc / seat sealing surface.
2) the position of the axis relative to the center line of the hole;
3) the axis of the valve seat cone angle deviating from the center line of the valve hole.

The combination of these three offsets provides a conical seal surface to minimize wear and tear between seats and seals and to improve the service life and sealing performance of the valve. In addition, reduce the valve seat's surface torque to the minimum and reduce the working torque of the valve.

Triple Eccentric Butterfly Valve

Generally speaking, because of its sealing characteristics and cost, it has more advantages than other metal seat valve types. Because of its compact structure, revolving design and lightweight structure, it can be installed and operated easily, and they do not need tube support. Replaceable sealing rings, allowing quick and simple maintenance and low torque (allowing smaller drives) mean more cost savings.
Two way zero leakage closed metal seat has only one soft seat valve. This will greatly expand the possibility of application. Flexible sealing rings and optimal torque transmission mean that these valves can provide fire safety design and sealing performance, which can be larger than the maximum temperature range of the general butterfly valve design. Traditionally, oil and gas processing, refining, chemical and petrochemical plants, power generation, offshore platforms, heating, papermaking, steel mills, sugar mills, desalination, water treatment and distribution may be found in many industries. Their use in all industries has increased stringent government regulations and greater production demand, forcing users to seek solutions. Consumption has risen steadily for decades, and features provide many good solutions, including those with greater challenges. These benefits include operational efficiency, wear resistant media and chemicals to a certain temperature or pressure, and versatility in a wide range of operating conditions.

Utilizing the features of the design, the next generation of design provides functions to further improve the safety and performance of the valve, including:
1, the use of precision machined sealing surface and sealing ring to form metal to metal seal. Even in high temperature and high pressure and other harsh service environment, two-way seal and zero leakage can be achieved. Low friction and streamlined standard right-angle cone design, metal-to-metal can solve thermal expansion and contraction well, is an important feature of high temperature and high pressure environment services. Metal to metal seals are allowed to be used in oil fields with fire protection requirements.
2. The best design of seating surface is that the seating surface of the valve body is welded with Stellite cemented carbide. The seating surface has longer service life and better wear resistance, even if it is used repeatedly. The design of the sealing structure reduces friction with the butterfly plate and reduces the working torque.
3. Special valve seat design uses valve to automatically adjust valve seal. The floating seal ring and a wide sealing ring support gasket are more reliable by using sealing and opening and closing. The valve seat ensures that the valve has two way sealing characteristics.
4. The positioning pin of the valve design is located at a very low position of the butterfly plate, allowing good performance in thermal expansion and minimizing the disturbance of the valve stem to the greatest extent. Therefore, valves have a long service life.
