一．Product Introduction
The Manual Segment Ball Valve is a specialized valve designed for precise flow control and shut-off in industrial applications. Characterized by its segmented ball structure, it combines the advantages of a ball valve’s ease of operation and a control valve’s flow regulation capability. This valve is manually operated via a lever, making it suitable for scenarios where automated actuation is not required or where simplicity and reliability are prioritized. It is widely used in industries such as natural gas, petroleum, chemical, and pipeline systems, where manual control of media flow (including gases, liquids, and some slurries) is needed.
二．Product Features
- Precise Flow Regulation: The segmented ball design allows for accurate throttling and control of flow rates, providing a linear flow characteristic that enables fine adjustments to media flow.
- Reliable Sealing Performance: Equipped with high-quality sealing components, the valve ensures tight shut-off with minimal leakage, even under varying pressure conditions.
- Robust and Durable Construction: The valve body and segmented ball are typically fabricated from materials like carbon steel, stainless steel, or alloy steel, offering resistance to corrosion, wear, and high pressures, thus ensuring a long service life.
- Easy Manual Operation: The integrated lever handle enables quick and effortless manual operation, allowing for on-site control without the need for external power sources.
- Wide Media Compatibility: Available in various material configurations, it can handle different media, including corrosive, viscous, and particulate-containing fluids, making it adaptable to diverse industrial environments.
- Low Flow Resistance: The streamlined internal design minimizes pressure drop, facilitating efficient media transport and energy conservation.
- Simple Maintenance: Its straightforward structure allows for easy disassembly and maintenance, reducing downtime and operational costs.
三．Technical Data
