At present, the Triple Eccentric Butterfly Valve which we often see on the market has experienced the evolution from the traditional midline butterfly valve to the Single-eccentric butterfly valve and the double-eccentric butterfly valve, and finally formed the present Triple Eccentric Butterfly Valve. At present, Triple Eccentric Butterfly Valve are mainly used in metallurgical, electric power, petrochemical, municipal, gas and drainage systems.

The sealing surface of the Triple Eccentric Butterfly Valve has uniform force and high pressure bearing capacity under closed condition, and no jamming phenomenon occurs during the opening process. The action of separating the sealing surface of the butterfly plate from the seat at all points of the sealing surface is basically non-frictional; the opening moment is very low, the structure is compact, the cost is low, and the service life is long; it can realize two-way flow with adjustment and long life. Cut off function. Therefore, Triple Eccentric Butterfly Valve are used in various important pipelines such as process control in petrochemical industry.

Noticeable Problems in Selection and Use of Triple Eccentric Butterfly Valve
Applicable occasions: suitable for large caliber, large flow and low pressure difference occasions. Applicable fluids: Applicable to concentrated turbid liquids and fluids containing suspended particles. Sealing Material Selection: Corrosive fluids require the use of corrosive materials.
Application of Triple Eccentric Butterfly Valve in Chemical Plant
The normal control ratio of the Triple Eccentric Butterfly Valve is more than 2 times that of the general butterfly valve, and the maximum control ratio can be as high as 100:1, which creates a good condition for the use of the Triple Eccentric Butterfly Valve as the control valve. Especially in the case of large caliber, the cost of globe valve is extremely high, and the globe valve can not achieve zero leakage. In the case of emergency shutdown, the cut-off valve must be installed at the side of the globe valve. The Triple Eccentric Butterfly Valve can be integrated with regulation and shutdown (to achieve zero leakage), and its economic benefits are very considerable. It has been tested in practice and successfully applied in polyethylene plant. Typical applications: Reactor cooler temperature regulation (as shown in Figure 3), process pipeline for large diameter 18 (1"to 25.4 mm), normal temperature regulation, Triple Eccentric Butterfly Valve as a common control valve, when interlocking occurs, Triple Eccentric Butterfly Valve plays a cut-off role, and completely shut off (zero leakage). At this time, the Triple Eccentric Butterfly Valve integrates regulation and shutdown. From the operation of the device, it not only saves the investment cost, but also controls it stably, which brings great economic benefits to the enterprise.
Triple Eccentric Butterfly Valve has been continuously improved. Now the Triple Eccentric Butterfly Valve we use not only has excellent cutting performance, but also can be applied to the requirements of media diversity through different sealing forms.
