Double Eccentric Offset Disc Butterfly Valve: High-Performance Engineering by FlowBiz Exports

In modern fluid dynamics, the Double Eccentric Butterfly Valve (also known as the Double Offset Valve) is the superior choice for high-pressure systems and large-diameter pipelines. FlowBiz Exports Pvt Ltd is a leading Double Eccentric Butterfly Valve manufacturer in India, providing state-of-the-art engineering solutions that ensure zero-leakage and extended service life.

Understanding the Double Eccentric (Double Offset) Design

The "Double Eccentric" design features two distinct offsets in the valve geometry that prevent friction between the disc and the seat.

  1. Offset 1: The shaft is located behind the centerline of the sealing surface.
  2. Offset 2: The shaft is located to one side of the pipe/valve centerline.

Why FlowBiz Offset Valves Lead the Industry:

  • Friction-Free Sealing: The disc "lifts" off the seat immediately upon opening, drastically reducing seat wear and extending the valve's operational life.
  • Low Operating Torque: The offset geometry reduces the force required to open and close the valve, making it ideal for automation.
  • Tight Shut-Off: Our PTFE seats combined with FEP/PFA lining offer a "bubble-tight" seal even in corrosive environments.
  • Full Flow Downstream: Designed for multiple ON/OFF operations in extensive pipelines with minimal pressure drop.
