Understanding Flanged Butterfly Valves
Flanged butterfly valves feature flanged ends that allow for easy connection to pipelines using bolts and gaskets. The flanged design provides a secure and reliable connection, making these valves suitable for a wide range of applications.
• Flanged End Connections: Flanged ends facilitate easy installation and replacement, reducing downtime and maintenance costs.
• High Pressure and Temperature Resistance: Suitable for high-pressure and high-temperature applications, ensuring reliable performance.
• Ease of Maintenance: Flanged butterfly valves are easy to access for maintenance and inspection, simplifying repair processes.
• Versatility: Suitable for a wide range of applications, including water treatment, HVAC systems, and industrial processes.
• ASME B16.5: Flanged butterfly valves must comply with ASME B16.5 standards for flanged end connections, ensuring compatibility and interchangeability.
• Gasket Selection: Proper gasket selection is crucial to ensure a tight seal and prevent leaks.
• Bolt Tightening: Bolts must be tightened evenly and to the specified torque to ensure a secure connection.
• Tight Sealing: Flanged butterfly valves provide excellent sealing performance, ensuring minimal leakage and maintaining system integrity.
• Leakage Rate: Very low leakage rate, suitable for applications requiring zero leakage.
Understanding Wafer Butterfly Valves
Wafer butterfly valves feature wafer or wafer end connections that allow them to be sandwiched between two flanges. The wafer design provides a secure connection and ensures proper alignment with the pipeline.
• wafer End Connections: Wafer ends allow the valve to be sandwiched between two flanges, providing a secure and reliable connection.
• Compact Design: Wafer butterfly valves have a compact design, making them suitable for space-constrained applications.
• High Pressure and Temperature Resistance: Suitable for high-pressure and high-temperature applications, ensuring reliable performance.
• Ease of Installation: Easy to install and replace, reducing downtime and maintenance costs.
• ASME B16.34: Wafer butterfly valves must comply with ASME B16.34 standards for wafer end connections, ensuring compatibility and interchangeability.
• Gasket Selection: Proper gasket selection is crucial to ensure a tight seal and prevent leaks.
• Bolt Tightening: Bolts must be tightened evenly and to the specified torque to ensure a secure connection.
• Tight Sealing: Wafer butterfly valves provide excellent sealing performance, ensuring minimal leakage and maintaining system integrity.
• Leakage Rate: Very low leakage rate, suitable for applications requiring zero leakage.
