Full Lug Type Butterfly Valve
Product Overview:
The Full Lug Type Butterfly Valve is designed for reliable flow control in various industrial and commercial applications. It features a full lug design that allows it to be mounted between flanges with bolts. This provides a secure and stable connection. The valve handles different pressures and temperatures while maintaining efficient operation.
Design Standards:
– API 609: Defines design, materials, and testing requirements for butterfly valves. This ensures performance and reliability.
– ASME B16.34: Specifies pressure-temperature ratings, materials, and design criteria for valves in pressure-containing applications.
– ISO 5752: Provides dimensions and performance standards for butterfly valves. This ensures compatibility with international piping systems.
Structural Features:
– Full Lug Design: The lugs extend beyond the flange faces. This design allows the valve to be securely bolted to the flanges, reducing the need for additional gaskets or seals.
– Body Material: Available in materials such as cast iron, carbon steel, and stainless steel. The choice depends on the application requirements and media compatibility.
– Disc Mechanism: Features a quarter-turn operation for precise flow control and minimal pressure drop.
Sealing Mechanism:
– Soft Seal Option: Uses resilient materials like EPDM (Ethylene Propylene Diene Monomer) or PTFE (Polytetrafluoroethylene) for sealing in standard applications. Suitable for water and mild chemicals.
– Hard Seal Option: Constructed from metal or other durable materials for high pressure, high temperature, or aggressive media. Provides a robust seal for harsh conditions.
Applications:
– Water Distribution: Ideal for water supply and treatment systems. Provides reliable isolation and flow control.
– Industrial Processes: Suitable for various industrial applications requiring robust valve performance.
– HVAC Systems: Used in heating, ventilation, and air conditioning systems for efficient flow regulation.
Usage Conditions:
– Operating Pressure: Designed to handle pressures up to 150 psi (10 bar). The pressure rating may vary based on material and design.
– Temperature Range: Operates within a temperature range from -10°C to 120°C (14°F to 248°F). Temperature limits depend on seat material and application specifics.
Additional Features:
– Corrosion Resistance: The materials resist corrosion, enhancing durability and reducing maintenance.
– Ease of Maintenance: The full lug design allows easy installation, removal, and maintenance without disrupting the piping system.
Summary:
The Full Lug Type Butterfly Valve is designed for dependable performance. It conforms to API 609, ASME B16.34, and ISO 5752 standards. The valve features a full lug design for secure installation and is available in both soft and hard seal options. It is suitable for various media and operating conditions, including water distribution, industrial processes, and HVAC systems.
