TWT Triple eccentric butterfly valves with many features and benefits to oversea market. Now, let us comprehend it.

Eccentric Butterfly Valves By TWT

Eccentric butterfly valves are a type of butterfly valve that incorporates an offset between the center of the disc and the center of the valve seat. This design feature provides several advantages over concentric butterfly valves.

Eccentric Butterfly Valves With Wide Range Of Dimensions

The size range of eccentric butterfly valve can vary depending on the manufacturer and specific valve design. Normally, minimum size from DN15 (1/2 inch) or DN20 (3/4 inch), maximum size is up to DN1200 (48 inches) or even larger DN1800 (72 inch). However, TWT provides quality eccentric type butterfly valve, size is from 2.5 inch up to 72 inches. Certainly, it should depend on buyers requirement. Please contact us for valve dimension you need.

Advantages of Eccentric Butterfly Valves

  1. Improved Sealing Performance:
  • The offset design creates a tighter seal between the disc and the valve seat, reducing the risk of leakage.
  • Eccentric butterfly valves are suitable for applications requiring high sealing integrity, such as vacuum systems or high-pressure applications.
  1. Reduced Wear and Tear:
  • The offset design minimizes contact between the disc and the valve seat, reducing wear and tear on the valve components.
  • This can extend the service life of the valve and reduce maintenance requirements.
  1. Lower Operating Torque:
  • The eccentric design reduces the torque required to operate the valve, making it easier to open and close.
  • This can be particularly beneficial in large-diameter valves or applications where manual operation is preferred.
  1. Better Flow Control:
  • The eccentric design provides more precise flow control compared to concentric butterfly valves.
  • This is because the offset disc creates a gradual change in the flow area as the valve is opened or closed.

Quality Triple Eccentric Butterfly Valves With EN593 Standard

Triple eccentric butterfly valve is a specialized type of eccentric butterfly valve that incorporates three offsets:

  • Offset between the center of the disc and the center of the valve seat.
  • Offset between the center of the disc shaft and the center of the valve body.
  • Offset between the center of the disc shaft and the center of the disc.

These multiple offsets provide even greater sealing performance, reduced wear and tear, and improved flow control compared to standard eccentric butterfly valves. Aiming to triple design valve’s Materials, Normal diameter, End connection, we may satisfy customers demand according to own OEM and custom service.

Butterfly Valves: Cast Iron Materials – Functions As Eccentric And Center Line Types

Butterfly Valves: Cast Iron Materials – Functions As Eccentric And Center Line Types

Butterfly valves have become a prevalent flow control option across many industries due to their compact design and smooth operation. Within the waterworks sector, butterfly valves find application for main line isolation, throttling, and branch selection. Their versatile usage stems from configurations that suit a variety of installation requirements. Two prominent butterfly valve variations are the center line and eccentric styles, each excelling under certain conditions based on their internal structures.

High Quality Cast Iron Vavles Butterfly Design

center line butterfly valve supplier

At the foundation of a robust butterfly valve design are high quality cast iron materials. Ductile iron remains the predominate choice for valve bodies due its elastic properties that withstand cyclical stresses. Cast iron butterfly valve conforms well to tight radii and complex geometries like those contained within eccentric butterfly valves. Additionally, ASTM A126 Grade B ductile iron possesses sufficient strength for underground applications where compaction pressures can deform lesser metals.

Butterfly Valve Variations – Centerline VS. Eccentric

While the previous post focused on gate valves, it’s also worth reviewing some of the common types of butterfly valves used in similar underground applications. Butterfly valves provide flow isolation using a pivoting disc instead of a gate.

There are two main categories of butterfly valve designs – centerline and eccentric:

In a centerline butterfly valve, the disc rotates about an axis that runs directly through the center of the valve body and disc. This style offers precise sealing along the axis no matter the flow direction.

However, for tight bends or branches in the piping where space is limited, an eccentric butterfly valve can be an option. In an eccentric design, the disc axis is offset above or below the horizontal centerline of the valve body.

For Applications Where Reduced Envelope Is Paramount

Eccentric butterfly valves offset the rotational axis away from center. This inclined orientation shaves wall thickness from the typical butterfly valve shape. Eccentric butterfly valves excels in situations like throttling service, where flow direction remains constant after valve installation. Their truncated form slips into confined chambers such as flow control vaults or meter bypass manifolds. However, the canted disc alignment causes reduced shut-off capability when flow passes through the open valve in both directions. Therefore, eccentric butterfly valves find more specialized usage than center line types.

Turning to valve flowpath variations, center line butterfly valve orient closure members along the symmetrical midline of flow. Advantageously, this center mounted design enables bi-directional shut-off without compromising seal integrity. Center line butterfly valves function effectively as main isolating valves where flow reverses in pumping systems.
