In industrial valve systems, butterfly valves are widely appreciated for their compact design, cost-effectiveness, and quick shutoff capability. But not all butterfly valves are created equal.
At Anson Flow, we offer a full range of concentric, double eccentric, and triple eccentric butterfly valves offered in Wafer, Lug, and Flanged types to accommodate different pipeline installation needs.
—each engineered to meet the specific demands of water, chemical, oil & gas, and other industrial applications.
🔍 What Are the Differences Between Concentric and Eccentric Butterfly Valves?
1 1️⃣ Concentric Butterfly Valve
Design Features:The stem and disc share the same centerline. Simple structure with reliable sealing performance.
Seat Materials:Suitable for water treatment, HVAC, food processing, and similar applications.
Typical Applications:Low-pressure, ambient temperature systems such as municipal water supply, environmental engineering, and ventilation systems.
2️⃣ Double Eccentric Butterfly Valve
Design Features:The stem is offset in two directions. When opening, the disc quickly disengages from the seat, minimizing friction and wear.
Performance Advantages:Ideal for medium-pressure applications. Offers long service life, lower torque requirement, and stable flow control.
Application Fields:Industrial circulation water, chemical fluids, fire protection systems, and other environments requiring enhanced sealing and pressure resistance.
3️⃣ Triple Eccentric Butterfly Valve
Design Features:Adds a third offset with a conical sealing surface, achieving a metal-to-metal seal.
Performance Advantages:Withstands high temperature, high pressure, fire, and corrosion. Achieves zero leakage performance.
Typical Industries:Petrochemical, refining, power plant steam systems, and seawater desalination applications.
