Product Overview

The Pneumatic Flanged Soft Sealed Butterfly Valve (D641X) features an innovative design and a simple structure, allowing for rapid opening and closing with easy operation. It is characterized by its compact size, lightweight, low resistance, high flow capacity, and reliable performance. With various attachments, it can achieve automated control, and its bidirectional sealing structure ensures zero leakage. The installation direction is not limited by the medium flow direction. This product is widely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, chemical, and water treatment.

Product Features  

1. Excellent bidirectional sealing performance, low torque, and superior machining quality.  
2. Flow characteristics tend toward linearity, providing good adjustment performance.  
3. Convenient flanged connection for both vertical and horizontal installation.  
4. Variety of sealing materials available for user selection.  
5. The valve can be used as a drain valve at the pipe end, ensuring reliable performance.  
6. The sealing ring integrates organically with the valve body, extending the valve's lifespan.  
7. Good abrasion resistance, suitable for harsh working conditions, and can be used for media cutoff and adjustment.
