High-Performance LYE Double Eccentric Flanged Butterfly Valve for Precise Fluid Regulation

Introducing the LYE Double Eccentric Flanged Butterfly Valve, a high-performance solution engineered for optimal fluid control. This advanced butterfly valve features a double offset eccentric design, ensuring superior functionality and longevity. Ideal for various industrial applications, the LYE Butterfly Valve is your go-to choice for reliable and efficient fluid management.

Key Features and Benefits

1. Double Offset Configuration:
   • The valve incorporates a double offset design, with two offsets located away from the centerline. This innovative configuration ensures that the disc does not contact the rubber seal when in the open position, significantly reducing wear and tear.
2. Streamlined Disc Design:
   • The disc features a streamlined shape, minimizing water head loss when the valve is fully open. Its smooth surface reduces resistance to flow, enhancing overall efficiency.
3. Reliable Sealing Performance:
   • Equipped with a one-piece rubber disc edge seating, the valve provides exceptional sealing performance, ensuring durability and long-term reliability.
