China Double Offset Butterfly Valve

  • Enhanced performance, reliability and durability.
  • Optimize flow control efficiency.
  • Securely sealed.
  • Innovative features and sturdy construction

Product Description

A double offset butterfly valve, as its name suggests, features two offsets in its design. The first offset is between the centerline of the disc and the stem, which reduces the friction and wear on the seat during operation. The second offset places the axis of the disc slightly behind the center of the sealing surface, thus minimizing contact with the seat when the valve is partially open. This unique configuration allows for reduced torque, lower seat wear, and improved sealing performance, especially under high-pressure and high-temperature conditions.

Features of China Double Offset Butterfly Valve

  • Double Offset Design: The double offset configuration of these valves refers to the offset of both the shaft and the disc from the centerline of the valve body.
  • Bubble-Tight Sealing: The double offset design enables the valve to achieve a bubble-tight seal with minimal torque, enhancing performance and minimizing the risk of leakage in critical applications.
  • High-Performance: These valves can handle high-pressure differentials without causing excessive wear on the sealing surfaces.


1. Precise Flow Control: The double offset design allows for precise modulation of flow rates, making these valves ideal for applications that require accurate control over fluid flow.

2. Enhanced Sealing Performance: With their bubble-tight sealing capability, these valves provide reliable shut-off and leak-free operation, ensuring system integrity and safety.

3. Longevity and Durability: Constructed from high-performance materials, China Double Offset Butterfly Valves offer exceptional durability, resisting wear and corrosion for extended service life.

4. Versatile Applications: These valves are suitable for a wide range of industries, including oil and gas, chemical processing, water treatment, power generation, and more, due to their versatility and reliability.
