1. High Strength with Ductile Iron Body
The valve body is made from ductile iron, offering excellent tensile strength and impact resistance. Compared to cast iron, ductile iron provides better flexibility and durability under pressure. This allows the valve to perform reliably in both low- and high-pressure systems.
2. Space-Saving Wafer Design
The wafer type connection is compact and lightweight. It fits easily between standard flanges, requiring minimal installation space. This makes it ideal for tight or limited-access areas, while also reducing overall system weight.
3. Fast Operation and Tight Sealing
With a quarter-turn operation, the DI wafer butterfly valve enables fast opening and closing. Paired with a resilient seat material (like EPDM, NBR, or PTFE), it ensures a tight, bubble-free seal—making it suitable for both on/off and throttling service.
4. Low Maintenance and Easy Replacement
The valve's structure is simple, often consisting of just a few main components—body, disc, seat, and stem. Many models feature replaceable seats and discs, reducing maintenance time and costs. Its corrosion-resistant body and components also extend service life.
5. Wide Application Versatility
DI wafer butterfly valves are compatible with a wide range of media, including water, air, gas, and light chemicals. They are commonly used in pipelines for water supply, fire protection, air conditioning systems, and more. Their ability to handle different pressures and temperatures makes them a flexible solution for various systems.
Conclusion
The DI Wafer Butterfly Valve is a modern valve solution that combines performance, economy, and ease of use. Its durable construction, compact design, and reliable sealing make it a top choice in many industrial and commercial applications. For engineers seeking long-term value with minimal complexity, the DI wafer butterfly valve is a smart, proven investment.
