High-performance butterfly valves (HPBV) are a specialized type of butterfly valve designed to withstand demanding conditions, including high pressures, high temperatures, and severe service applications.

Design and Construction:

• • High-performance butterfly valves are available in various designs, including concentric, double offset, and triple offset configurations. Each design offers different levels of performance, with triple offset designs providing the highest level of performance and sealing integrity.
• • High-performance butterfly valves feature robust construction with heavy-duty materials and advanced design features to ensure reliable performance in challenging environments.

Materials of Construction:

• • High-performance butterfly valves are typically made from high-quality materials such as stainless steel, carbon steel, alloy steel, or exotic alloys, depending on the application requirements.
• • The choice of material depends on factors such as the fluid being handled, temperature, pressure, corrosion resistance requirements, and compatibility with other system components.

Applications:

• • High-performance butterfly valves are used in a wide range of industries and applications where reliable performance and tight shut-off are essential.
• • They are commonly installed in power plants, chemical processing plants, oil and gas refineries, petrochemical facilities, HVAC systems, and water treatment plants, among others.

Double flanged butterfly valves are a specific type of butterfly valve characterized by having flanges on both ends of the valve body.

Design and Construction:

• • Double flanged butterfly valves feature a disc (or butterfly) mounted on a shaft in the center of the valve body.
• • The valve body is designed with flanges on both the upstream and downstream ends, allowing for easy installation between flanged pipe connections.
• • The disc is positioned perpendicular to the flow when the valve is closed and parallel to the flow when the valve is fully open.

Materials of Construction:

• • Double flanged butterfly valves are available in a variety of materials to suit different application requirements, including carbon steel, stainless steel, cast iron, ductile iron, PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), and other alloys.
• • The choice of material depends on factors such as the fluid being handled, temperature, pressure, corrosion resistance requirements, and compatibility with other system components.

Applications:

• • Double flanged butterfly valves are used in a wide range of industries and applications where reliable flow control and tight shut-off are required.
• • They are commonly installed in water and wastewater systems, HVAC systems, chemical processing plants, power generation facilities, and other fluid handling systems.

Wafer lugged butterfly valves are a specific type of butterfly valve designed with lugs or ears on the valve body to facilitate installation and ensure proper alignment within a piping system.

Design and Construction:

• • Wafer lugged butterfly valves feature a disc (or butterfly) mounted on a shaft in the center of the valve body.
• • The valve body is designed with lugs or ears on the outer circumference, which allow the valve to be secured between two flanges using bolts and nuts/li>
• • The lugs provide additional support and stability, ensuring proper alignment and preventing movement or rotation of the valve within the pipeline.

Materials of Construction:

• • Wafer lugged butterfly valves are available in a variety of materials to suit different application requirements, including carbon steel, stainless steel, cast iron, ductile iron, PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), and other alloys.
• • The choice of material depends on factors such as the fluid being handled, temperature, pressure, corrosion resistance requirements, and compatibility with other system components.

Applications:

• • Wafer lugged butterfly valves are used in a wide range of industries and applications where reliable flow control and tight shut-off are required.
• • They are commonly installed in water and wastewater systems, HVAC systems, chemical processing plants, power generation facilities, and other fluid handling systems.

Wafer butterfly valves are a type of butterfly valve designed to fit between two flanges in a pipeline without the need for additional support or mounting brackets.

Design and Construction:

• Wafer butterfly valves consist of a circular disc (or butterfly) mounted on a shaft in the center of the valve body.
• The valve body is designed with lugs or ears on the outer circumference, which allow the valve to be sandwiched between two flanges using bolts and nuts.
• This design eliminates the need for flange mounting brackets, making installation simpler and more cost-effective.

Applications:

• Wafer butterfly valves are commonly used in industries where space and cost considerations are important factors, such as HVAC systems, water and wastewater treatment plants, chemical processing plants, and food and beverage processing facilities.
• They are suitable for handling a wide range of fluids, including water, air, gases, and light slurries.
