Exploring Different Types of Butterfly Valves: U-Type, Center Line, and Extension Stem

Jan 16, 2024 | News


Butterfly valves are essential components used in various industries for fluid flow control. The U Type butterfly valve provides low resistance to flow, making it suitable for applications where efficiency is crucial. Center Line butterfly valves offer reliable sealing and are versatile for both high and low-pressure applications. Extension Stem butterfly valves allow for remote operation, ensuring safety and convenience in hard-to-reach locations.

Section 1: U-Type Butterfly Valve

U-Type butterfly valves are characterized by their unique U-shaped disc design. This design allows for a streamlined flow path, minimizing pressure drop and turbulence. The U-Type butterfly valve is ideal for applications where low resistance to flow is essential, such as in HVAC systems, water treatment plants, and industrial processes. Its compact size, lightweight construction, and ease of installation make it a popular choice for a wide range of applications. Additionally, the U-Type butterfly valve offers excellent flow control capabilities and reliable sealing performance.

Section 2: Center Line Butterfly Valve

Center Line butterfly valves are designed with the disc centered in the pipe, providing a bi-directional shutoff. This design ensures equal pressure distribution across the disc, resulting in improved sealing performance and reduced wear. Center Line butterfly valves are versatile and suitable for both high and low-pressure applications. They find extensive use in industries such as oil and gas, chemical processing, and water distribution systems. The center line design allows for easy maintenance, as the valve can be installed and removed without disturbing the pipeline.

Section 3: Extension Stem Butterfly Valve

Extension Stem butterfly valves are designed with an extended stem that allows for remote operation. This type of valve is commonly used in applications where the valve is located in hard-to-reach or hazardous areas. The extension stem enables the operator to control the valve’s position from a safer and more convenient location. Extension stem butterfly valves are widely utilized in industries such as oil and gas, petrochemical, and wastewater treatment plants. They offer excellent flow control, durability, and reliable sealing performance.
