Pneumatic Lug Butterfly Valve
Product Overview:
The Pneumatic Lug Butterfly Valve is built for high-performance applications. It offers precise flow control and reliable operation. Equipped with a pneumatic actuator, this valve is ideal for automated systems. It delivers quick and efficient performance. The valve’s robust construction and advanced features make it suitable for various industrial environments.
Pneumatic Actuator Parameters:
– Operating Pressure: 40-120 psi (2.8-8.3 bar)
– Control Options: Available in both single-acting (spring return) and double-acting configurations.
– Material: Actuators are typically made from aluminum or stainless steel. This provides durability and resistance to corrosion.
– Operating Temperature: -20°C to 80°C (-4°F to 176°F), with options for higher temperature ranges.
– Positioning: Adjustable positioners allow for precise control. Options for 4-20 mA feedback are available for integration into automated control systems.
Lug Design Standards:
– API 609: This standard covers design, materials, and testing requirements. It ensures the valve meets high-performance standards.
– ASME B16.34: Specifies pressure-temperature ratings, materials, and design criteria. It applies to valves used in pressure-containing applications.
– ISO 5752: Provides dimensions and performance standards. Ensures compatibility with international piping systems.
Lug Connection Method:
– Advantages:
– Secure Installation: The valve bolts directly to the flanges, providing a stable and reliable connection.
– Maintenance Flexibility: Allows for easy removal and replacement of the valve without disturbing the piping on either side.
– System Isolation: Enables isolation of either side of the piping system. This allows for maintenance without shutting down the entire system.
– Disadvantages:
– Higher Cost: Lug-style valves are often more expensive due to the additional material and complexity in design.
– Increased Weight: The design requires more material, which can make the valve heavier. This may be a limitation in some installations.
High-Performance Features:
– Sealing Mechanism: The valve offers both soft and hard sealing options. Soft seals are typically made from EPDM, PTFE, or similar materials. They are ideal for water, air, and mild chemical applications. Hard seals, usually made of metal, are suitable for high-pressure, high-temperature environments.
– Double Offset Design: This design minimizes friction between the disc and the seat. It reduces wear and extends the valve’s lifespan. It also ensures a bubble-tight shutoff, which is essential for critical applications.
Media and Operating Conditions:
– Compatible Media: The valve handles a wide range of media. This includes water, steam, gases, and aggressive chemicals. The choice of seal material should be based on the specific media and operating conditions.
– Operating Conditions: The valve performs well under high-pressure and high-temperature environments. It is capable of withstanding extreme conditions, ensuring reliable operation and long-term durability.
Summary:
The Pneumatic Lug Butterfly Valve is a high-performance solution. It is designed for automated flow control in demanding industrial applications. The valve adheres to key industry standards like API 609, ASME B16.34, and ISO 5752. This ensures quality and reliability. The lug connection method provides secure installation and maintenance flexibility. The pneumatic actuator allows for precise and efficient operation. With options for both soft and hard sealing, this valve handles a wide range of media and operating conditions. Its advanced design and robust construction make it an excellent choice for industries that require reliable and durable valve solutions.
