Three Eccentric Structure Description
The Three Eccentric Butterfly Valve features a unique three-eccentric design:
– Structure: This design involves three key offsets—the shaft axis, the valve seat, and the center of the valve body. These offsets create a camming action that reduces friction and wear.
– Operation: As the valve rotates, the disc moves away from the seat before sealing. This minimizes contact and extends the valve’s lifespan.
Advantages and Disadvantages of Three Eccentric Design
Advantages:
- Reduced Wear: The design minimizes friction between the disc and the seat. This reduces wear and extends the valve’s lifespan.
- Improved Sealing: Provides a tight seal even under high-pressure conditions. Ensures zero leakage.
- High Performance: Capable of withstanding high temperatures and pressures. Suitable for demanding applications.
- Durability: Reduces the need for frequent maintenance. Extends the valve’s operational life.
Disadvantages:
- Complexity: The mechanism is more complex compared to traditional butterfly valves. This can increase manufacturing costs.
- Initial Cost: Generally more expensive due to the advanced design and materials.
- Size Limitation: Might not be suitable for very large valve sizes or low-pressure applications.
