A ball valve is a type of valve that uses a hollow, perforated, and pivoting ball to control the flow of a fluid or gas. The ball is typically made of metal and has a hole drilled through it, which lines up with the flow of the fluid when the valve is open, and is perpendicular to the flow when the valve is closed. Ball valves are often used in industrial settings, as well as in plumbing and natural gas pipelines. They are easy to operate and can be used for both on/off control and throttling purposes. The full bore and reduced bore are the two common types of ball valve.
Socket ball valves, flanged ball valves, and worm-gear ball valves are all types of ball valves that are used for specific applications.
A socket ball valve is a type of ball valve that has a socket connection. This connection type is typically used for smaller-diameter pipes and allows for easy installation and removal of the valve.
A flanged ball valve is a type of ball valve that has a flange connection. This connection type is typically used for larger-diameter pipes and allows for easy installation and removal of the valve. It also allows for a better seal and can handle higher pressure and temperature compared to socket connection.
A worm-gear ball valve is a type of ball valve that is operated by a worm gear drive. This allows for precise control of the valve position and is typically used in applications where precise control is important, such as in industrial process control. The worm gear drive can be manual or motorized.
All of these valves have a ball inside that rotates to control the flow of fluid through the pipe, and they can be used to shut off or regulate the flow of fluid or gas.

Flanged Ball Valve Industrial Applications
Flanged ball valves are widely used in the chemical industry for controlling the flow of acids, alkalis, solvents, and other reactive fluids. Our flanged ball valves are designed with high-performance plastics, specialty alloys, and non-metallic materials that resist chemical attack and mechanical wear, extending service life and reducing the frequency of maintenance. The full bore design allows for unobstructed flow in high-volume pipelines, while reduced bore configurations provide precise control in smaller lines. Our valves are resistant to scaling, corrosion, and erosion, ensuring consistent performance in aggressive environments. Flanged connections provide robust support and leak-free operation, even under fluctuating pressure and temperature conditions. In chemical fiber production, our valves control the flow of raw chemicals with precision, ensuring uniform reaction conditions. In electroplating, flanged ball valves maintain stable chemical flow for coating consistency, while in specialty chemical plants, they enable accurate dosing and mixing of reactive compounds. Materials such as PTFE, PFA, and reinforced thermoplastics are selected based on the chemical properties of the fluid, its temperature, and pressure. Advanced sealing systems, such as double O-rings and spring-loaded seats, provide reliable shutoff and minimize leakage. Valve bodies are designed to withstand cyclic stress from thermal expansion and contraction. The smooth internal surface reduces turbulence, erosion, and contamination. By combining material science, engineering precision, and rigorous testing, our flanged ball valves operate safely and efficiently in pipelines transporting highly corrosive, viscous, or abrasive fluids.

In pharmaceutical manufacturing, flanged ball valves are used in process lines handling active pharmaceutical ingredients, solvents, purified water, and intermediates. Our valves are made from corrosion-resistant plastics and metal alloys compatible with clean-in-place (CIP) and sterilization-in-place (SIP) processes, ensuring contamination-free flow. Smooth internal surfaces prevent biofilm formation, and precise sealing mechanisms reduce leakage, protecting product quality and operational reliability. Full bore flanged valves support high-flow applications, while reduced bore designs allow accurate throttling for precise dosing or batch transfers. Our valves are compatible with automation systems, enabling integration into controlled production lines with real-time monitoring. Temperature-resistant materials allow operation under steam sterilization, high-temperature cleaning, and chemical sanitization. Valves are designed to minimize dead zones, facilitating complete drainage and cleaning. In formulation lines, flanged ball valves provide consistent flow rates that are critical for maintaining product uniformity. The valves’ durability reduces the need for frequent replacement, minimizing process interruptions. In addition, modular design simplifies maintenance, allowing rapid replacement of seats, seals, or stems without removing the entire valve from the system. The ability to operate reliably under fluctuating pressures and temperatures ensures that production lines maintain throughput without compromising safety or quality. Our valves’ chemical resistance and precise engineering make them suitable for pharmaceutical intermediates, high-purity solvents, and large-scale water-for-injection systems.
