Understanding Trunnion-Mounted Ball Valves
Trunnion-mounted ball valves are a type of ball valve designed with a fixed ball supported by a trunnion, which enhances stability and reduces operational torque. This design allows for precise control and reliable sealing, making them ideal for high-pressure and high-flow applications. The valve consists of a valve body, a fixed ball, a stem, seats, and seals.
• Fixed Ball Design: The ball is fixed and does not move, providing stable operation and reducing wear.
• Reduced Operational Torque: The trunnion support reduces the torque required to operate the valve, making it easier to open and close.
• Reliable Sealing: The design ensures tight sealing, minimizing leakage and ensuring efficient water distribution.
Diameter Compatibility in Municipal Water Networks
DN50 to DN1200: Range and Applications
Trunnion-mounted ball valves are available in a wide range of diameters, from DN50 to DN1200, making them suitable for various applications in municipal water networks. These applications include:
• Water Distribution Pipelines: Ensuring efficient flow control and reliable isolation in main distribution lines.
• Pump Stations: Controlling flow rates and protecting pumps from backflow.
• Reservoirs and Tanks: Managing water levels and preventing overflow.
• Fire Protection Systems: Providing reliable isolation and control in fire suppression systems.
Diameter-Specific Considerations
• Applications: Suitable for smaller distribution lines, service connections, and branch lines.
• Advantages: Compact size, ease of installation, and cost-effectiveness.
• Installation: Ensure proper alignment with the pipeline and secure mounting to prevent leaks.
• Applications: Ideal for medium-sized distribution lines and secondary mains.
• Advantages: Higher flow capacity, reliable operation, and reduced maintenance.
• Installation: Requires careful handling and alignment to ensure proper seating and sealing.
• Applications: Suitable for main distribution lines and critical junctions.
• Advantages: High flow capacity, robust design, and long-term reliability.
• Installation: Professional installation is recommended to ensure proper alignment and secure mounting.
• Applications: Ideal for large-diameter main lines, reservoirs, and major pumping stations.
• Advantages: Exceptional flow capacity, high-pressure handling, and reliable isolation.
• Installation: Requires specialized equipment and expertise to ensure proper installation and alignment.
