Double Eccentric Butterfly Valve with EPDM Seat Material and Electric Operation for Temperature Range -10 to 80°C

Product Description:

The Double Eccentric Butterfly Valve is a highly reliable and efficient valve designed for a wide range of industrial applications. Constructed with a robust ductile iron body, this valve offers excellent strength and durability, ensuring long-lasting performance even in demanding environments. The ductile iron material not only provides superior resistance to impact and corrosion but also maintains structural integrity under varying pressure conditions, making it an ideal choice for fluid control systems.

This butterfly valve features a double eccentric design, which significantly enhances its sealing performance and reduces wear on the sealing components. The double eccentric mechanism means that the valve disc is offset twice from the centerline of the pipe and the centerline of the valve shaft. This unique configuration minimizes contact between the disc and the seat during operation, resulting in lower friction, smoother operation, and extended service life. The double eccentric design also provides a tighter seal compared to traditional concentric valves, making it suitable for applications requiring reliable leak-tight closure.

Equipped with an EPDM seal, the valve ensures excellent sealing properties and chemical resistance. EPDM (Ethylene Propylene Diene Monomer) is known for its flexibility, durability, and resistance to water, steam, and a wide variety of chemicals. This seal material is especially effective in water treatment, HVAC systems, and other applications where resistance to weathering and aging is critical. The EPDM seal contributes to the valve's ability to maintain a secure and leak-free shutoff, enhancing overall system efficiency and safety.

The Double Eccentric Butterfly Valve is versatile in its operation, offering multiple actuator options to suit different application needs. Users can choose from manual operation for straightforward, hands-on control, gear operation for increased torque and ease of use in larger sizes, or electric operation for automated and remote control capabilities. This flexibility allows the valve to be seamlessly integrated into various control systems, enhancing operational convenience and precision.

Designed to meet international standards such as BS (British Standards) and ANSI (American National Standards Institute), this valve complies with stringent quality and performance criteria. These standards ensure that the valve is manufactured to high specifications, guaranteeing compatibility, safety, and reliability across different industrial sectors. Whether used in water supply, chemical processing, or HVAC systems, the valve meets the necessary regulatory requirements and industry benchmarks.

The valve’s connection type is flange, providing a secure and easy means of installation and maintenance. Flanged connections offer strong mechanical strength and allow for quick disassembly when servicing or replacing the valve. This feature is particularly beneficial in complex piping systems where frequent maintenance or inspection is required. The flange connection also ensures tight sealing with the pipeline, preventing leaks and maintaining system integrity.

Pressure ratings for this Double Eccentric Butterfly Valve range from PN10, PN16, to PN25, allowing it to operate efficiently under various pressure conditions. This range caters to low to medium pressure applications, making the valve suitable for a broad spectrum of industrial processes. Whether it is used in water distribution, chemical handling, or HVAC systems, the valve’s pressure ratings ensure reliable performance and safety under operational stresses.

Another notable feature of this product is the bare head design, which refers to the valve’s exposed stem or shaft without additional coverings or enclosures. This design simplifies inspection and maintenance, allowing operators to easily monitor the condition of the valve components. The bare head also facilitates straightforward manual operation and quick identification of any mechanical issues, contributing to reduced downtime and maintenance costs.

In summary, the Double Eccentric Butterfly Valve with a ductile iron body, EPDM seal, and bare head construction is a versatile, durable, and high-performance valve solution. Its compliance with BS and ANSI standards, multiple operation modes, flange connection, and wide pressure rating range make it an excellent choice for various industrial applications. Whether controlling water flow, managing chemical processes, or regulating HVAC systems, this valve delivers reliable sealing, easy operation, and long-term durability, ensuring optimal system performance and safety.
