Triple Eccentric Butterfly Valve

Valvesonly Europe is the leading Triple Eccentric Butterfly Valve Manufacturers in Germany. The triple eccentric butterfly valve is a crucial component in pipelines, providing precise control over fluid flow. Unlike conventional butterfly valves, which feature a centered disc rotation axis, the triple eccentric design introduces additional levels of sophistication.

This valve is characterized by three distinct offsets:

  • Shaft Offset: The shaft of the valve is positioned off-centre from the centreline of the pipeline, ensuring a non-interference rotation of the disc.
  • Disc Offset: The disc is offset from the shaft centreline in two directions – one perpendicular to the flow direction and the other at an angle to ensure a tight seal.
  • Seal Ring Offset: The seal ring is strategically positioned away from the seat during the valve’s operation, minimizing friction and wear.

Distinguishing Features

  • Enhanced Sealing Performance: The triple eccentric configuration enables the valve to achieve a bubble-tight seal, even in high-pressure and high-temperature environments. This superior sealing capability reduces leakage and enhances operational safety.
  • Improved Durability: By minimizing friction and wear, the triple eccentric design prolongs the valve’s service life, resulting in reduced maintenance requirements and downtime.
  • High Flow Capacity: The streamlined flow path offered by the triple eccentric butterfly valve minimizes pressure drop across the valve, allowing for efficient fluid transport and optimized system performance.

Differentiating Triple Eccentric from Double Eccentric

While both triple eccentric and double eccentric butterfly valves serve the same fundamental purpose, they exhibit significant differences in design and functionality:

  • Number of Offsets: As the names suggest, the primary distinction lies in the number of offsets. Double eccentric valves feature two offsets – one for the shaft and one for the disc – whereas triple eccentric valves incorporate an additional seal ring offset.
  • Sealing Performance: Triple eccentric valves offer superior sealing performance compared to their double eccentric counterparts. The triple offset design ensures a tighter seal, minimizing the risk of leakage even under challenging operating conditions.
  • Friction and Wear: With its additional offset, the triple eccentric butterfly valve experiences reduced friction and wear on critical sealing components. This translates to extended service life and enhanced reliability, particularly in demanding industrial applications.
  • Operating Torque: Triple eccentric valves typically require higher operating torque compared to double eccentric valves due to their more complex design. However, this trade-off is justified by the valve’s superior performance and longevity.
