Metal Seated Flanged Ball Valve Description
The closing member (ball) of a metal-seat flanged ball valve is driven by the stem and rotates around the stem's axis. When the stem pushes the valve core (ball), the core moves along the valve seat, controlling the medium flow by adjusting its position. In practical applications, the rotation angle of this valve is typically 90 degrees. When the stem rotates the ball by 90°, the ball's passage aligns or disconnects from the valve seat's channel, enabling opening or closing of the valve.
Metal-Seat Flanged Ball Valve Features:
Excellent Sealing Performance: The tight contact between the valve seat and ball effectively prevents fluid leakage.
Easy Operation: A simple 90-degree rotation completes the opening/closing action, making it ideal for quick on/off applications.
Low Flow Resistance: The ball's through-hole matches the pipe diameter, minimizing flow resistance.
High Durability: The valve body and ball are typically made of corrosion-resistant materials, suitable for various media.
Easy Maintenance: The simple structure allows for easy disassembly and replacement of components.

Function of Metal-Seat Flanged Ball Valves
Metal-seat flanged ball valves are critical fluid control valves primarily used to regulate and shut off high/low-pressure steam, liquids, and gases. Their key functions include:
Flow Regulation – By adjusting the opening/closing degree of the flanged ball valve, flow can be controlled to meet varying operational requirements.
Fluid Shutoff – When the medium flow reaches a certain level, the valve can be closed to stop the flow, preventing hazards or leaks.
Pressure Regulation – Under different inlet/outlet pressures, the flanged ball valve helps stabilize system pressure by adjusting the medium flow.
