Application
The VT-N Ductile Iron Butterfly Valve Gearbox is a robust and versatile valve commonly used in industrial applications. Constructed with high-quality ductile iron, this valve exhibits excellent strength and durability, making it suitable for handling various media, including water, gases, and corrosive fluids.
The inclusion of a gearbox enhances the valve’s performance by providing smooth and precise control over the flow of fluids. The gearbox mechanism allows for easy manual operation, allowing users to adjust the valve’s position quickly and efficiently. This feature is especially beneficial in situations where frequent adjustments are required to regulate the flow rate.
The Ductile Iron Butterfly Valve Gearbox design ensures minimal pressure loss, thanks to its streamlined disc and low-friction bearings. This design feature also promotes efficient flow control and reduces energy consumption. Additionally, the valve’s tight shut-off capabilities prevent any leakage, enhancing its reliability and safety.
