4 Inch Lug Style Butterfly Valve
Product Overview:
The 4 Inch Lug Style Butterfly Valve is designed for efficient flow control in various applications. It features a lug-style connection, making it suitable for flanged pipe systems. This valve ensures reliable performance and durability in demanding environments.
Design Standards:
– API 609: Specifies design, materials, and testing requirements for butterfly valves.
– ASME B16.34: Covers pressure-temperature ratings, materials, and design specifications for valves.
– ISO 5752: Provides dimensions and performance standards for butterfly valves.
Structural Features:
– Lug Style Connection: This valve has threaded lug connections for easy installation and removal. The lug-style design allows mounting between flanges without additional gaskets or seals.
– Body Material: The valve body is typically made from cast iron, carbon steel, or stainless steel, depending on application needs and media compatibility.
– Disc Design: The valve features a quarter-turn operation mechanism. The disc ensures efficient flow control and minimal pressure drop.
Sealing Mechanism:
– Seat Options: Available in both soft seal and hard seal configurations. Soft seals are used for general applications, while hard seals are suitable for high-pressure or high-temperature conditions.
– Soft Seal: Made from resilient materials like EPDM (Ethylene Propylene Diene Monomer) or PTFE (Polytetrafluoroethylene). Offers effective sealing for a wide range of media.
– Hard Seal: Constructed from metal or other hard materials. Suitable for harsh conditions and aggressive media.
– Sealing Type: Ensures minimal leakage with secure sealing against the valve body and disc.
Applications:
– Water Systems: Suitable for water distribution and treatment. Provides reliable flow control and isolation.
– Industrial Processes: Ideal for various industrial applications that require robust flow regulation and durability.
– HVAC Systems: Used in heating, ventilation, and air conditioning systems. Offers effective flow control and energy efficiency.
Usage Conditions:
– Operating Pressure: Designed to handle pressures up to 150 psi (10 bar), depending on material and construction.
– Temperature Range: Operates effectively in temperatures from -10°C to 120°C (14°F to 248°F). Temperature range may vary based on seat material and application.
Additional Features:
– Corrosion Resistance: The valve body and components resist corrosion and wear, extending service life and reducing maintenance needs.
– Ease of Maintenance: The lug-style design allows easy removal and replacement of the valve. This simplifies maintenance and repairs without disturbing the piping system.
Summary:
The 4 Inch Lug Style Butterfly Valve offers efficient flow control and reliable performance. It meets industry standards like API 609, ASME B16.34, and ISO 5752. Available in soft and hard seal options, it adapts to various media and conditions. The lug-style connection ensures easy installation and maintenance.
