Product Overview

The Flanged Eccentric Butterfly Valve is designed to provide reliable control of fluid flow in a wide range of industrial applications. Featuring an eccentric design, this valve minimizes the wear and tear between the disc and seat, ensuring a longer service life and tight sealing performance. The valve body is made of durable materials, making it suitable for high-pressure and high-temperature environments. With its flanged connections, the valve can be easily installed and maintained in piping systems. The design also promotes low torque operation, offering efficient control and reducing energy consumption. This versatile valve is ideal for water treatment, chemical processing, and other demanding fluid control systems.

Product Features

Eccentric Design: The valve features a three-dimensional eccentric design, which reduces friction between the sealing surfaces, ensuring minimal wear and a longer service life.
Precise Sealing: Equipped with a high-quality elastomer or metal sealing ring, providing excellent sealing performance, even in high-pressure or low-temperature environments.
Durability: The valve body is made from high-strength materials such as cast iron, carbon steel, or stainless steel, ensuring reliability and longevity in demanding applications.
Smooth Operation: The unique eccentricity of the shaft allows for smooth and efficient operation with reduced torque requirements, providing ease of use and quicker opening/closing times.
Low Flow Resistance: The valve’s design optimizes the flow path, reducing turbulence and minimizing flow resistance, leading to energy savings in fluid handling systems.
Bidirectional Sealing: The flanged eccentric butterfly valve provides excellent bidirectional sealing, making it ideal for both flow directions without performance degradation.
Versatile Applications: Suitable for use in a variety of industries such as water treatment, HVAC systems, and chemical processing, thanks to its robust design and versatility.
Customizable Actuation: Compatible with a wide range of actuators, including manual, electric, pneumatic, and hydraulic drives, allowing for flexible installation and operation.
Compact Design: Its compact and lightweight construction makes it ideal for applications where space is limited, without compromising on performance.
Corrosion Resistance: Available in materials resistant to corrosion, ensuring reliable performance in harsh environmental conditions.
