ISO Certified Double Eccentric Butterfly Valve with Stainless Steel Disc and EPDM Seat for Precise Flow Control

Product Description:

The Double Eccentric Butterfly Valve is a highly reliable and efficient valve specially designed for water applications. Engineered to provide superior performance and durability, this valve is an ideal choice for controlling the flow of water in various industrial and municipal systems. The valve features a double eccentric design, which significantly reduces friction and wear on the sealing surfaces, thereby enhancing its operational lifespan and ensuring a tight, leak-proof seal even under high pressure conditions.

One of the key components of this valve is its disc, which is made from premium stainless steel. The stainless steel disc offers excellent resistance to corrosion, making it suitable for use in water systems where exposure to moisture and other environmental factors is constant. Additionally, the disc is equipped with a high-quality Steel Disc Ring that ensures a robust sealing surface and contributes to the valve’s overall reliability. The Steel Disc Ring is precision-engineered to provide a secure fit with the valve seat, minimizing the risk of leakage and improving the valve’s sealing performance over time.

The valve operates on a double eccentric principle, meaning the disc is offset from the valve body and the shaft, which reduces the contact area between the disc and the seat during opening and closing. This design not only decreases wear and tear but also enables smoother and more efficient operation. The valve is available in multiple operation modes to suit different installation requirements and user preferences. It can be operated manually through a bare head mechanism, allowing for straightforward and direct control. For applications requiring less manual effort or remote operation, the valve can also be equipped with a gear or electric actuator. The gear operation facilitates easier manual turning by providing mechanical advantage, while the electric operation allows for automated control, integration with control systems, and enhanced convenience.

Certified to meet stringent international standards, the Double Eccentric Butterfly Valve holds ISO, UL, and FM certifications. These certifications guarantee that the valve complies with globally recognized quality, safety, and performance criteria, making it a dependable choice for critical water applications. Whether used in water treatment plants, distribution networks, or industrial water systems, this valve ensures safe and efficient flow control.

The valve’s durable construction, combined with the corrosion-resistant stainless steel disc and the robust Steel Disc Ring, ensures longevity even in demanding environments. The bare head design option offers simplicity and ease of maintenance, while the availability of gear and electric operation modes provides flexibility and adaptability for various operational needs.

In summary, the Double Eccentric Butterfly Valve is a premium water valve solution that combines advanced engineering, high-quality materials, and versatile operation modes. Its stainless steel disc, enhanced by the Steel Disc Ring, delivers exceptional durability and sealing efficiency. The valve’s double eccentric design minimizes wear and maximizes performance, while certifications such as ISO, UL, and FM affirm its quality and reliability. Whether you require manual control through a bare head, or automated operation via gear or electric actuators, this valve offers a comprehensive solution for effective water flow management.
