Best 10 Triple Offset Butterfly Valve Manufacturers in the World

What Is Triple Offset Butterfly Valve?

Triple Offset Butterfly Valve, also known as Triple Offset Hard Seal Butterfly Valve, is an advanced butterfly valve design that is widely used in industrial and commercial applications. It achieves efficient sealing and low-torque operation through a triple eccentric structure. The design principle of triple eccentric butterfly valve is to deviate the contact surface between the butterfly plate and the valve seat from the center axis, so that the sealing surface no longer rubs when the valve is closed, which reduces wear and prolongs service life.

Benefits Of Triple Offset Butterfly Valve

Triple offset butterfly valve has excellent sealing performance. Its triple eccentric design ensures that the valve is completely leak-free when closed, and maintains excellent sealing effect even under high pressure and high temperature conditions, which complies with API 607 and API 6FA fire test standards and guarantees the safety and reliability of the system.

Triple offset butterfly valves are extremely durable. Since its sealing surface is metal-to-metal contact, it reduces friction and wear, making the service life of the valve significantly longer. In addition, this design can effectively prevent the medium from erosion and corrosion of the sealing surface, which improves the adaptability of the valve in harsh working conditions.

Three offset butterfly valve has flexible operation and low energy consumption. As the unique design reduces the friction during opening and closing, the operating torque is smaller, thus reducing the energy consumption and maintenance cost of the actuator.

Triple Offset Butterfly Valve has a wide range of applicability. It is not only suitable for conventional water, steam and oil and gas media, but can also handle fluids containing solid particles, meeting the needs of various complex working conditions.

How Does A Triple Offset Butterfly Valve Work?

The design of the Triple Offset Butterfly Valve is characterized by three eccentric (offset) positions between the valve plate and the valve seat, which ensures that the valve will not cause friction during opening and closing, prolonging service life and providing better sealing performance.

The first offset is the centerline deviation of the valve stem relative to the valve seat. This design avoids direct friction between the valve plate and the seat during opening and closing, resulting in smoother operation while reducing wear and torque requirements.

The Second Offset is where the sealing surface of the valve plate is offset from the centerline of the valve stem. This eccentric design allows the valve plate to quickly disengage from the seat during opening, reducing wear and operating resistance. This off-center position helps to achieve rapid opening and closing of the valve.

The Third Offset is a geometrical deviation between the seat surface and the sealing surface of the valve plate. This design allows the valve plate to move closer to the seat during the closing process until a tight metal-to-metal contact is achieved, resulting in a zero-leakage seal. The position of the third eccentric ensures that the valve can still maintain good sealing performance under extreme conditions such as high temperature and high pressure.

The working principle of the triple offset butterfly valve is based on the precise design and manufacture of the three eccentric positions mentioned above. During operation, the valve plate controls the flow of fluid by rotating 90 degrees. When the valve opens, the valve plate quickly leaves the valve seat, avoiding friction and wear; when the valve closes, the valve plate gradually moves closer to the valve seat, ultimately forming a tight metal-to-metal seal. This design not only improves the durability of the valve, but also provides excellent performance in harsh environments such as high pressure, high temperature and corrosive media.
