Gear Operated Double Eccentric Butterfly Valve with Flange Connection for -10 to 80℃ Temperature Range

Product Description:

The Double Eccentric Butterfly Valve is a highly reliable and efficient valve designed to regulate and isolate the flow of water in various industrial and municipal applications. Manufactured to meet strict international standards such as BS (British Standard) and ANSI (American National Standards Institute), this valve ensures superior performance, durability, and safety in operation. It is engineered to withstand a range of pressure ratings including PN10, PN16, and PN25, making it suitable for diverse water system requirements from low to medium pressure levels.

One of the standout features of this Double Eccentric Butterfly Valve is its innovative dovetail design. This design enhances the stability and alignment of the valve disc, reducing wear and tear over time and ensuring a longer service life. The dovetail configuration also contributes to a tighter seal, minimizing leakage and improving overall valve efficiency. This makes the valve an excellent choice for critical water control applications where reliability and tight shut-off are paramount.

The valve is available with a bare head or a valve worm gear, offering flexibility to suit different operational needs. The bare head option provides a straightforward valve mechanism that can be manually operated or easily automated with additional actuators. On the other hand, the valve worm gear available option allows for easier and more precise control, especially in larger valves or systems where manual operation would be cumbersome. The worm gear mechanism facilitates smooth and controlled valve movement, enhancing user convenience and operational accuracy.

Certified by internationally recognized bodies including ISO (International Organization for Standardization), UL (Underwriters Laboratories), and FM (Factory Mutual), this Double Eccentric Butterfly Valve meets rigorous quality and safety standards. These certifications attest to the valve’s excellent manufacturing quality, reliability, and compliance with safety regulations, making it a trusted choice for water applications worldwide.

Designed specifically for water applications, the valve is ideal for use in water treatment plants, distribution networks, irrigation systems, and other water management infrastructures. Its robust construction and precise engineering allow it to handle the unique demands of water flow control, including resistance to corrosion and erosion caused by waterborne particles. This ensures consistent performance and reduces maintenance requirements over the valve's operational lifespan.

The double eccentric design differentiates this butterfly valve from conventional single eccentric types by offsetting the valve disc from the centerline of the valve body and the pipe bore. This double offset reduces friction between the disc and the seat during operation, resulting in less wear and a more reliable sealing surface. Consequently, the valve offers improved durability and a longer operational life, making it a cost-effective solution for water system operators.

In summary, the Double Eccentric Butterfly Valve is a versatile, durable, and high-performance valve solution engineered for water applications. Meeting standards such as BS and ANSI, and pressure ratings from PN10 to PN25, it provides reliable flow control and isolation. The innovative dovetail design, coupled with options for a bare head or valve worm gear, ensures operational flexibility and superior sealing performance. Backed by ISO, UL, and FM certifications, this valve stands as a benchmark of quality and reliability in the water industry, making it an excellent investment for any water management system.
