As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our High-Performance Ductile Iron Butterfly Valve. Engineered to meet the rigorous demands of modern industrial applications, this valve combines the superior strength of ductile iron with the precision of an electric actuator, offering a robust and efficient flow control solution. Designed in strict compliance with the GB/T3036 standard, our valve ensures consistent performance and interchangeability, backed by our ISO9001 certified manufacturing processes. We understand that dependable valve operation is critical to your system's uptime, which is why we focus on delivering products that provide long-term value and operational peace of mind.
This valve is engineered for excellence, featuring several key characteristics that set it apart in the market:
- Superior Durability: The valve body and disc are constructed from high-grade ductile iron, known for its excellent tensile strength, impact resistance, and corrosion resistance compared to standard cast iron.
- Precise Electric Control: Equipped with a reliable 24V DC electric actuator, it allows for remote on/off or precise modulating control, integrating seamlessly into automated systems. The low-voltage DC operation enhances safety in various environments.
- Excellent Sealing Performance: The standard EPDM seat provides a tight, bubble-tight seal, suitable for a wide range of media including water, air, and mild chemicals. Alternative seat materials like NBR or Viton are available for specific fluid compatibility needs.
- Compact and Lightweight Design: The wafer or lug style design offers a space-saving and weight-reducing advantage, simplifying installation and reducing structural support requirements.
- Low Operating Torque: The streamlined disc design and quality bearing system ensure low friction and minimal torque requirement, which prolongs actuator life and reduces energy consumption.
- Easy Maintenance: The design allows for easy inspection and replacement of the seat seal without removing the valve body from the pipeline, significantly reducing maintenance downtime and cost.
Our valve delivers tangible benefits to your operations:
- Enhanced System Reliability: Minimizes leakage risks and unplanned shutdowns.
- Improved Process Efficiency: Enables precise flow regulation for optimized system performance.
- Reduced Total Cost of Ownership: Durable construction and low maintenance needs lead to long-term savings.
- Simplified Integration: Standard interfaces and control signals allow for straightforward integration into new or existing control systems.
Below is a summary of key technical specifications for common sizes:
| Nominal Diameter (DN) | Approx. Weight (kg) | Standard Pressure Rating | Actuator Operating Time (Seconds, Open to Close) |
|---|---|---|---|
| DN50 (2") | ~5.5 | PN16 | ~15 |
| DN100 (4") | ~9.0 | PN16 | ~20 |

Frequently Asked Questions (FAQ)
-
Q: What are the main advantages of using a ductile iron body over cast iron?
A: Ductile iron offers significantly higher tensile strength, better impact resistance, and improved elongation properties. This makes the valve more durable, less prone to cracking under stress or water hammer, and suitable for a wider range of demanding applications. -
Q: Is the 24V DC electric actuator suitable for hazardous areas?
A: The standard 24V DC actuator is intrinsically safer due to its low voltage and is commonly used in many industrial settings. However, for certified use in specific hazardous (classified) areas, explosion-proof or intrinsically safe certified actuators can be offered as an optional configuration. Please specify your area classification requirements. -
Q: Can this valve be used for throttling or flow control, not just on/off?
A: Yes. While the standard configuration is for on/off service, a modulating version of the electric actuator is available as an option. This allows for precise proportional control (e.g., 4-20mA or 0-10V input) to regulate flow rates accurately. -
Q: Does the valve come with a manual override feature?
A: Yes, most of our electric actuators include a manual handwheel or lever for manual operation in case of power failure or for maintenance purposes, ensuring operational continuity. -
Q: What is the lead time for standard sizes and bulk orders?
A: For standard sizes (DN50-DN300) and common configurations, we typically maintain stock for prompt shipment. Lead times for larger sizes or custom orders vary but are generally competitive. We provide specific timelines upon receipt of your detailed inquiry. -
Q: Are spare parts like seals and gaskets readily available?
A: Absolutely. We provide comprehensive after-sales support and maintain an inventory of critical spare parts, including seat seals (EPDM, NBR, Viton) and gaskets, to ensure minimal downtime for our customers. -
Q: What fluids/media is the standard EPDM seat compatible with?
A: The standard EPDM seat is suitable for a wide range of media including cold and hot water, air, steam (up to 120°C), weak acids, alkalis, and alcohols. For aggressive chemicals, oils, or high-temperature applications beyond its range, we recommend optional seat materials like Viton or PTFE. -
Q: Do you offer valves with different end connections besides wafer/lug?
A: The standard design is wafer or lug for ease of installation. However, flanged ends or other connection types can be accommodated as a custom modification to meet specific project piping requirements.
