12 – Inch Double Eccentric Butterfly Valve

 

12-inch double eccentric butterfly valve for high-pressure flow control and pipeline sealing, Vcore valveProduction Overview

The 12 – Inch Double Eccentric Butterfly Valve from Vcore Valves is designed for high-performance flow control in large-scale industrial applications. Featuring a double eccentric design, this valve offers improved sealing capabilities and smoother operation, making it ideal for controlling the flow of fluids, including water, oil, gas, and chemicals.

The double eccentric design ensures that the valve’s disc does not come into contact with the seat during operation, reducing wear and tear, and extending the valve’s lifespan. This unique feature minimizes the risk of leakage and ensures a tighter seal, even under high-pressure conditions. The 12-inch diameter makes it suitable for large pipeline systems, while the butterfly disc allows for easy on/off control or modulating flow.

The 12 – Inch Double Eccentric Butterfly Valve operates using a rotating disc inside the valve body. The double eccentric design means that the axis of the valve stem is offset from the centerline of the disc and seat, ensuring that the disc does not touch the seat during operation, which reduces wear, minimizes friction, and provides a tighter seal. This feature enhances the valve’s performance, particularly in applications where leakage control is critical.

When the valve is open, the disc rotates to align with the flow path, allowing the fluid to flow freely. When the valve is closed, the disc rotates to block the flow and forms a tight seal against the seat. The valve’s full-bore design ensures that fluid flows through with minimal resistance and pressure drop when the valve is open.

Constructed from high-quality materials like stainless steel, ductile iron, and cast iron, the Double Eccentric Butterfly Valve is durable and reliable, providing a cost-effective solution for industries requiring efficient fluid control with minimal maintenance.
