Butterfly Valves – Which One Is Better Between Triple Offset And Double Offset

Nov 8, 2023 | News

Both triple offset butterfly valves and double offset butterfly valves offer reliable performance in industrial applications. China Double offset butterfly valves provide versatility and reliable performance in various operating conditions, while triple offset butterfly valves excel in high-pressure and high-temperature environments, offering a tight bubble-tight seal. So If we know about butterfly valves well, we can make informed decisions when selecting the most suitable valve for specific industrial processes, such as oil and gas, chemical processing, water treatment, and more.

What Is Butterfly Valve?

A butterfly valve is a type of quarter-turn valve used for regulating or isolating the flow of fluid in a pipeline. The design of a butterfly valve is relatively simple yet effective. When the disc is perpendicular to the flow direction, it creates a full closure, effectively stopping the flow. There are two types of butterfly valves below:

1. Double Offset Butterfly Valves: Performance and Versatility
  1. a) Offset Design: Double offset butterfly valves feature a unique offset design where the shaft is positioned slightly off-center from the center of the valve disc.
  2. b) Sealing Performance: The offset design of double offset butterfly valves allows for improved sealing performance.
2. Triple Offset Butterfly Valves: Enhanced Performance and Tight Seal

Triple offset butterfly valves offer advanced performance and a tight seal, making them an excellent choice for demanding industrial applications.

  1. a) Eccentric Geometry: Triple offset butterfly valves feature an eccentric disc that is designed to achieve a tight seal with minimal friction.
  2. b) Zero Leakage: Triple offset butterfly valves are renowned for their zero-leakage capabilities. The unique geometry of the valve disc, combined with the metal seat, ensures a tight seal even under high-pressure and high-temperature conditions.
  3. c) High-Temperature and High-Pressure Applications: Triple offset butterfly valvesexcel in high-temperature and high-pressure applications.
