Metal Double Offset Butterfly Valve
A Metal Double Offset Butterfly Valve (also known as a high-performance butterfly valve) is engineered with a disc offset from both the centerline of the shaft and the body seat. This double eccentric design minimizes seat wear by reducing friction during operation, allowing for longer service life, bubble-tight sealing, and improved performance under high-pressure and high-temperature conditions. Manufactured from strong metals like stainless steel, carbon steel, or alloy steel, these valves are ideal for demanding industrial applications involving steam, gas, or aggressive liquids.
Key Features of Metal Double Offset Butterfly Valve
- Double Offset Design: Reduces contact between the disc and seat during operation, ensuring low torque and extended seat life.
- High-Performance Sealing: Provides bi-directional bubble-tight shutoff.
- Durable Metal Construction: Suitable for high pressure and high temperature applications.
- Quarter-Turn Operation: Enables quick opening and closing.
- Corrosion and Wear Resistant: Engineered for harsh industrial environments.
- End Connection Versatility: Available in wafer, lug, or flanged configurations.
- Automation Compatibility: Operable by lever, gear, pneumatic, or electric actuators.
- Long Service Life: Reduced friction ensures durability and reliable performance.
