Wafer Lug Type Butterfly Valve
Product Overview:
The Wafer Lug Type Butterfly Valve is a highly efficient flow control device designed for various industrial applications. It combines the benefits of wafer-style connections with excellent sealing performance. Suitable for a range of media and conditions, this valve offers both soft and hard sealing options. Its robust construction ensures reliable performance in demanding environments.
Design Standards:
– API 609: The valve meets the API 609 standard, which specifies requirements for butterfly valves used in general industrial applications. This ensures high performance and reliability.
– ASME B16.34: Compliant with ASME B16.34, this standard covers pressure-temperature ratings, materials, and design specifications, ensuring the valve can handle required pressure and temperature ranges in various industrial settings.
– ISO 5752: The valve adheres to ISO 5752, which defines face-to-face dimensions for butterfly valves. This ensures compatibility with international pipeline systems.
Wafer Lug Connection Method:
– Advantages:
– Compact Design: The wafer lug connection method is compact and occupies less space, making it suitable for installations in confined pipeline systems.
– Cost-Effective: Compared to full lug valves, the wafer lug design uses fewer bolts, reducing material costs and installation time.
– Easy Maintenance: The valve can be easily removed for maintenance without dismantling an entire side of the pipeline system.
– Disadvantages:
– Limited Pressure Handling: The wafer lug design may not be as strong as full lug valves, making it more suitable for medium to low-pressure applications rather than high-pressure environments.
– Potential Leakage Risk: There may be a higher risk of leakage compared to full lug valves. The connection does not fully surround the pipe, which may affect sealing performance on both sides.
Sealing Options:
– Soft Sealing: The valve can be equipped with soft seals, typically made of EPDM or PTFE. Soft seals are suitable for water, air, and mild chemicals, offering excellent sealing performance for low to medium pressure and temperature conditions.
– Hard Sealing: For more demanding applications, the valve can be fitted with hard seals, usually made from metal. Hard seals provide better resistance to high pressure, high temperature, and corrosive media, making them ideal for steam, hot gases, and other harsh conditions.
Media and Operating Conditions:
– Media Compatibility: The Wafer Lug Butterfly Valve is compatible with a wide range of media, including water, air, steam, gases, and various chemicals. The choice of soft or hard sealing should be based on the specific media and operating conditions.
– Operating Conditions: The valve is designed for medium pressure and temperature conditions, depending on the type of seal. It maintains sealing integrity and operational reliability in extreme environments.
Summary:
The Wafer Lug Type Butterfly Valve is an economical and efficient flow control solution for industrial use. Manufactured in accordance with API 609, ASME B16.34, and ISO 5752 standards, it ensures performance and compatibility. While the wafer lug connection offers installation and maintenance advantages, it may not be suitable for high-pressure applications. The valve provides both soft and hard sealing options to address different media and conditions, making it reliable for water treatment, chemical processing, and general industrial applications.
