As a professional manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our DIN 3352 PN10/PN16 Gate Valve in Ductile Iron. Established in 2016 and backed by ISO9001 certification, we have built a solid reputation for delivering robust fluid control solutions to global markets including North America, Europe, Southeast Asia, and beyond. This full port gate valve is engineered specifically for demanding water system applications, offering superior flow control, minimal pressure drop, and long-term durability. We understand the critical need for reliable shut-off in municipal, commercial, and industrial settings, and this valve is designed to meet that need head-on.
Our valve combines a time-tested design with modern manufacturing precision. The full port design ensures an unobstructed flow path, which is crucial for maintaining system efficiency and reducing pumping costs. Constructed from high-grade ductile iron, it provides an excellent balance of strength, impact resistance, and corrosion resistance, making it suitable for a wide range of water services, from potable water to industrial process water.
Key Features & Technical Advantages:
- Robust Construction: The ductile iron body and bonnet offer high tensile strength and good ductility, significantly reducing the risk of cracking under pressure or impact compared to standard gray iron.
- Superior Sealing Performance: Features a resilient seat (soft seal) that ensures bubble-tight shut-off. A metal seat version is available upon request for applications with higher temperatures or containing solids.
- Full Port Design: The bore diameter matches the pipeline ID, minimizing flow turbulence and pressure loss. This design is ideal for systems where flow efficiency is paramount.
- Smooth Operation: The rising stem design with a precision-machined trapezoidal thread provides clear visual indication of valve position (open/closed) and ensures smooth, low-torque operation over the valve's lifetime.
- Durable Coating: Standard epoxy coating provides excellent corrosion protection for both internal and external surfaces, extending service life in various environments.
- Flexible Actuation: Standard handwheel operation is ergonomic and reliable. For larger sizes or high-pressure applications, a gearbox operator is available as an option.
- Wide Compatibility: Compliant with DIN 3352 standard dimensions, ensuring easy installation and replacement in existing piping systems across many regions.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of using ductile iron over gray cast iron for this gate valve?
A: Ductile iron offers significantly higher tensile strength and impact resistance. It has good ductility (ability to deform without cracking), making it more suitable for applications with potential pressure surges or mechanical shock, thereby enhancing safety and longevity. -
Q: Can this valve be used for fluids other than water?
A: While designed primarily for water systems, its compatibility with other mild fluids (like air, oil, or certain chemicals) depends on the seal material. Please consult our technical team with your specific media details (temperature, chemical composition) for a definitive recommendation. -
Q: What does "Full Port" design mean, and why is it important?
A: "Full Port" (or Full Bore) means the internal diameter of the valve opening is essentially the same as the internal diameter of the connecting pipeline. This minimizes flow restriction, reduces pressure drop, and prevents clogging, which is crucial for maintaining system efficiency and for applications requiring pigging or high flow rates. -
Q: Is the valve suitable for underground burial or outdoor installation?
A: Yes, the standard epoxy coating provides good corrosion protection. For direct burial or particularly aggressive environments, additional coating options (like enhanced epoxy or polyethylene sleeve) may be available upon request. Always consider local soil conditions and regulations. -
Q: How do PN10 and PN16 pressure ratings relate to other standards like Class 150?
A: PN10 corresponds approximately to Class 150 in ANSI standards for lower temperature ranges. PN16 is a common European rating for 16 bar pressure at ambient temperature. It is essential to select the rating based on your system's maximum working pressure, including any safety factors. -
Q: Are the flanges drilled according to a specific standard?
A: Yes, the flanges are drilled according to DIN EN 1092-2, which is typical for PN10/PN16 flanges in European standards. This ensures compatibility with pipes and flanges from other manufacturers adhering to the same standard. -
Q: What is the delivery lead time for this product?
A: Lead times vary based on order quantity, size, and customization. Standard sizes are often available from stock or have shorter production cycles. We provide accurate lead time estimates upon receipt of your detailed inquiry. -
Q: Do you offer actuation options beyond the manual handwheel?
A: Absolutely. While supplied with a standard handwheel, this valve can be fitted with gear operators for easier manual operation of larger sizes. Furthermore, it can be adapted for electric, pneumatic, or hydraulic actuators. Please specify your actuation requirements when inquiring.
