Lugged Butterfly Valve
Product Overview:
The Lugged Butterfly Valve is engineered for robust and reliable flow control in various applications. Its design allows it to be bolted directly between flanges, providing a secure and stable connection. This valve is suitable for a wide range of industrial and commercial uses, offering versatility and ease of maintenance.
Design Standards:
– API 609: This standard covers the design, materials, and testing requirements for butterfly valves. It ensures that the valve meets high-performance standards.
– ASME B16.34: Specifies pressure-temperature ratings, materials, and design criteria for valves used in pressure-containing applications.
– ISO 5752: Provides dimensions and performance standards, ensuring compatibility with international piping systems.
Lugged Connection Method:
– Advantages:
– Secure Installation: The valve can be bolted directly to the flanges, providing a stable and reliable connection.
– Maintenance Flexibility: The design allows for the valve to be removed and replaced without disturbing the piping on either side.
– No Extra Gaskets Needed: The full lug design eliminates the need for additional gaskets, simplifying installation.
– Disadvantages:
– Cost: Lugged butterfly valves can be more expensive than wafer-style valves due to the additional material and design complexity.
– Space and Weight: The design may require more space and can be heavier, which might be a limitation in certain installations.
Sealing Options:
– Soft Seal:
– Materials: Typically made from EPDM, PTFE, or similar materials.
– Applications: Suitable for water, air, and mild chemical applications. Ideal for low to medium pressure and temperature conditions.
– Advantages: Provides excellent sealing with minimal leakage in standard conditions.
– Hard Seal:
– Materials: Typically constructed from metal, such as stainless steel or carbide.
– Applications: Suitable for high-pressure, high-temperature environments and aggressive media.
– Advantages: Offers robust and durable sealing for extreme conditions, ensuring a longer service life.
Media and Operating Conditions:
– Media: The valve can handle a variety of media, including water, steam, gas, and corrosive chemicals, depending on the selected seal type.
– Operating Conditions: Designed to perform in both low and high-pressure environments. It is effective in a wide range of temperatures, depending on the seal material used.
Additional Notes:
– Versatility: The lugged butterfly valve is suitable for both isolation and regulation of flow in various systems.
– Customization: Available in different materials and sizes to suit specific application needs.
– Durability: Designed for long-term use with minimal maintenance, especially when the appropriate seal type is selected based on the application.
Summary:
The Lugged Butterfly Valve is a versatile and reliable option for various industrial applications. It conforms to standards such as API 609, ASME B16.34, and ISO 5752. The valve offers the flexibility of soft or hard seals, which can be selected based on the specific media and operating conditions. Its secure lugged connection method ensures stability, while the design allows for easy maintenance and long-term performance.
