How to Select the Right Butterfly Valve for Your Application

Types of Butterfly Valves

Butterfly valves come in several designs, each suited for different applications:

Concentric (Resilient Seated)

The most common type, featuring a rubber-lined seat. Ideal for water, wastewater, and HVAC applications at low to moderate pressures.

Double Offset (High Performance)

Features an offset disc and shaft design that reduces seat wear. Suitable for higher pressure applications in oil & gas and chemical processing.

Triple Offset (Metal Seated)

The premium option with a metal-to-metal seal. Designed for the most demanding applications including high temperature, high pressure, and abrasive media.

Sizing Considerations

Proper sizing is critical for optimal performance. Key factors include:

• Flow rate requirements (Cv calculation)
• Pressure drop limitations
• Pipeline velocity constraints
• Actuator torque requirements
