Types of ductile iron double eccentric butterfly valve

The development of numerous butterfly valve design concepts now includes a variety of new butterfly valves. They are based on ductile iron double eccentric butterfly valve technology. These designs cover a wide range of forms such as U type butterfly valves and Lt butterfly valves:

  • Due to the simple design concept of the U-shaped butterfly valve, it is particularly suitable in environments where the requirements for valves are relatively relaxed. It is widely used because of its high opening and closing torque and good sealing performance. It is not only easy to use, but also quite simple to maintain.
  • Due to its excellent sealing characteristics and higher level of control precision, the L-type butterfly valve is especially suitable for occasions with high requirements on the sealing performance of the valve. It composes of valve body, valve seat and seals, which are susceptible to leakage during actual use. Due to the large influence of medium pressure and temperature changes, thus require regular maintenance and replacement. In many industries such as chemical and petroleum, its performance is the key to achieving optimal function.

Within industrial manufacturing, whether it’s a ductile iron double eccentric butterfly valve, a U-shaped butterfly valve, or an L-shaped butterfly valve, each fulfills a crucial function. Serving as quintessential pressure regulating valves, they adjust flow rates and vacuum levels according to the medium. These valves are pivotal in regulating fluid flow within piping systems, ensuring the uninterrupted stability of the production process. Their straightforward design and simple installation not only minimize maintenance and replacement costs but also enhance production efficiency.

In summary, the ductile iron double eccentric butterfly valve holds significant promise across various industrial applications. Thanks to its evident advantages and consistently robust performance, which demand attention and recognition. At present, TWT Valve has a certain number of ductile iron double eccentric butterfly valve products. There are already many engineering enterprises that have used our products for valve installation and overhaul work, and achieved good results.

A. Composition and Construction:

Ductile Iron: Ductile iron, also known as nodular cast iron, is a strong and highly durable material widely used in valve manufacturing. Its unique microstructure provides enhanced toughness, resistance to corrosion, and high tensile strength.

Double Eccentric Design: The double eccentric design of these butterfly valves refers to the off-center rotation of both the shaft and the disc. This design minimizes the friction between the disc and the seat, reducing wear and ensuring smooth operation.

B. Operating Principles:

Flow Regulation: Ductile iron double eccentric butterfly valves are designed to regulate the flow of fluids through a pipe or duct. By rotating the disc, the valve can be adjusted to control the flow rate, providing precise control over the fluid medium.

Leakage Prevention: The double eccentric design offers a tight seal, minimizing leakage when the valve is closed. This feature is particularly important in applications where leakage can lead to safety hazards, system inefficiencies, or environmental concerns.

Benefits and Advantages

A. Efficiency and Performance:

Smooth Flow Control: The double eccentric design of these valves allows for precise adjustment of flow rates. The reduced friction between the disc and seat ensures smooth operation and minimizes energy loss, enhancing overall system efficiency.

Low Pressure Drop: Ductile iron double eccentric butterfly valves by valve manufacturers in China, have a streamlined flow path, resulting in minimal pressure loss across the valve. This characteristic allows for efficient fluid transportation, reducing energy consumption and optimizing system performance.
