一．Product Introduction
The Resilient Seat V notch Ball Control Valve is a sophisticated control valve designed for precise flow regulation, throttling, and on-off control in various industrial applications. It integrates the advantages of a ball valve’s structural simplicity and a V-notch design’s excellent flow control performance, along with a resilient seat for reliable sealing. This valve is widely used in industries such as petrochemical, water treatment, pharmaceutical, and food processing, where accurate flow control and tight shut-off are essential. It can handle a variety of media, including liquids, gases, and even some slurries, making it a versatile choice for process control systems.
二．Product Features
- Precise Flow Control: The V-notch design of the ball enables precise throttling and control of flow rates. It provides a linear or equal percentage flow characteristic, depending on the notch design, allowing for accurate adjustment of media flow.
- Reliable Sealing: Equipped with a resilient seat, the valve offers excellent sealing performance, ensuring minimal leakage even under low-pressure conditions. The seat material is selected for its durability and compatibility with different media.
- Robust Construction: The valve body and ball are typically made from high-quality materials such as cast steel, stainless steel, or special alloys, ensuring resistance to corrosion, wear, and high pressures/temperatures, thus extending the service life.
- Wide Media Compatibility: It can handle various media, including corrosive, viscous, and particulate-containing fluids, due to the adaptable seat and ball materials.
- Actuation Options: Compatible with multiple actuation systems, such as pneumatic (as shown in the image), electric, or hydraulic actuators, allowing integration into different automated control systems for remote and precise operation.
- Low Flow Resistance: The streamlined design of the valve ensures low pressure drop, which helps in energy conservation and efficient media transport.
- Easy Maintenance: Its simple structure allows for easy disassembly and maintenance, reducing downtime and operational costs.
三．Technical data
