Triple Offset Laminated Seal Butterfly Valve is a high-performance valve, which is mainly used for the control of high temperature, high pressure or strong corrosive media. Due to its unique structural design, the triple eccentric multi-level butterfly valve has excellent sealing, flow control and regulation performance, so it is widely used in petroleum, chemical industry, electric power and other fields.

The main feature of the Triple Offset Laminated Seal Butterfly Valve is the use of eccentric structure design, by changing the degree of eccentricity, to achieve the control of the flow. At the same time, a multi-level sealing structure is adopted between the butterfly plate and the sealing ring, so as to ensure the reliability and tightness of the valve. In addition, the material of the valve is made of high-strength, corrosion-resistant materials, which can withstand the erosion of high temperature, high pressure and corrosive media, and has good durability.

When the valve is in the closed state, the eccentric angle of the butterfly plate of the triple eccentric multi-level butterfly valve makes it deviate from the center of the valve spindle, which reduces the operating force and friction, which is conducive to the opening and closing operation of the valve, and increases the sealing performance. When the valve is open, the contact area between the butterfly plate and the seat is reduced, which reduces the flow resistance and energy consumption of the liquid.

There are three different structural types of Triple Offset Laminated Seal Butterfly Valve: single eccentric, double eccentric and triple eccentric. Among them, the triple eccentric butterfly valve is the latest valve structure, and its butterfly plate outer ring eccentricity, inner ring oblique eccentricity and central axis deviation are all manifestations of its eccentricity. Compared to double eccentric and single eccentric butterfly valves, triple eccentric butterfly valves offer superior performance in terms of fluid control and tightness.

In short, the Triple Offset Laminated Seal Butterfly Valve is a high-performance valve with comprehensive functions and excellent performance, its special eccentric design and multi-level sealing structure provide a reliable guarantee for the control and flow regulation of various media, and is suitable for gas, liquid and steam medium in the guide fluid, which is an indispensable key device in modern industrial production.
