Product Description

A triple offset butterfly valve is a type of valve used in various industries to control the flow of fluids, such as water, gases, and chemicals. The "triple offset" design refers to three key features that set it apart from other butterfly valves:

  1. First Offset: The axis of the valve stem is offset from the centerline of the valve body. This means the valve seat and disc are not aligned with the center of the valve body, which reduces friction and wear during operation.

  2. Second Offset: The seat plane is offset from the centerline of the valve body. This offset helps to minimize the contact area between the disc and the seat, which reduces the torque required to operate the valve and increases its lifespan.

  3. Third Offset: The disc is rotated around an axis that is perpendicular to the seat plane. This rotation helps to achieve a tight seal by allowing the disc to move away from the seat as it opens, and then seal tightly against it as it closes.

These offsets contribute to a few key advantages:

  • Improved Sealing: The design minimizes leakage and provides a tight seal, which is particularly important in high-pressure and high-temperature applications.
  • Reduced Wear: Because the disc does not rub against the seat during operation, wear and tear are reduced, extending the valve's service life.
  • Low Torque: The offset design requires less torque to operate the valve, which can lead to more efficient use of energy and reduce the need for larger actuators.

Triple offset butterfly valves are often used in industries such as oil and gas, chemical processing, and power generation, where reliable performance and durability are crucial.

Triple offset butterfly valves come in various types based on their design and application. Here are some common types:

  1. Concentric Triple Offset Valve: The disc and seat are designed to align concentrically with the valve body. This type is often used in high-pressure applications.

  2. Lug Style Triple Offset Valve: Features lugs on the valve body that allow it to be bolted between flanges, making it suitable for situations where the valve needs to be easily removed or replaced.

  3. Wafer Style Triple Offset Valve: Designed to fit between flanges without additional lugs, it's often used in more compact installations.

  4. Double Flanged Triple Offset Valve: Equipped with flanges on both ends, this type is used in applications where the valve needs to be securely connected to piping systems.

Each type is designed to handle specific pressures, temperatures, and media, so the choice depends on the application's requirements.
