As a leading manufacturer with a strong track record since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering robust industrial flow control solutions. Our Ductile Iron Flanged Gate Valve, compliant with DIN 3352 and available from DN50 to DN300, is engineered for reliability in demanding applications. Designed for precise shut-off in water, oil, gas, and slurry pipelines, this valve combines the strength of ductile iron with a flanged connection for secure, leak-free installation. We serve a global clientele across diverse markets, backed by a commitment to quality certified under ISO9001 standards, ensuring every valve meets stringent performance criteria.
This gate valve is a cornerstone for industrial piping systems requiring dependable isolation. Its primary function is to provide a tight seal in the fully closed position, allowing or completely stopping the flow of media. The flanged ends facilitate easy integration into existing pipelines using standard bolts and gaskets, making installation and maintenance straightforward.
Key Features & Technical Advantages:
- Superior Material Strength: The valve body is constructed from high-grade ductile iron (also known as nodular cast iron), which offers excellent tensile strength, impact resistance, and durability compared to standard gray cast iron. This material choice significantly extends the valve's service life, especially in systems with potential pressure surges or mechanical stress.
- Precise Flow Control & Tight Seal: The valve employs a rising stem design with a wedge or parallel slide gate. When fully closed, the gate seats firmly against the valve body, creating a bubble-tight seal that prevents leakage. The non-rising handwheel design (optional rising stem available) is common for easier operation in confined spaces.
- Broad Compatibility & Standard Compliance: Manufactured in strict accordance with DIN 3352 F4/F5 standards, this valve ensures dimensional interchangeability and performance predictability. The size range from DN50 (2") to DN300 (12") covers most common industrial pipeline requirements.
- Versatile Application Range: Suitable for a wide array of media including water, wastewater, oil, gas, steam (within temperature limits), and mild slurries. Its robust construction makes it ideal for use in water treatment plants, chemical processing, power generation, irrigation systems, and building services.
- Corrosion Resistance & Protection: Standard valves feature an epoxy coating or other protective finishes on the exterior to guard against atmospheric corrosion. Internal components like the stem are typically made from stainless steel (e.g., SS304 or SS316) to resist corrosion from the media.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of using ductile iron over gray cast iron for this valve?
A: Ductile iron offers superior mechanical properties, including higher tensile strength, better impact resistance, and greater elongation. This makes the valve more durable and less prone to cracking under pressure shocks or physical stress, ensuring a longer service life. -
Q: Are these valves suitable for potable water applications?
A: Yes, they can be used for potable water. We can provide valves with appropriate internal epoxy coatings or linings (such as Fusion Bonded Epoxy) and use certified elastomers like EPDM for the seat, which are compliant with relevant drinking water standards. Please specify this requirement when ordering. -
Q: Can you provide valves with different flange standards, like ANSI?
A: Absolutely. While the standard offering is DIN/EN flanges, we frequently manufacture valves with ANSI B16.5 flanges (150lb, 300lb) or other standards like BS, JIS, or AS upon request. Customization of flange standards is a common service we provide. -
Q: What is the lead time for an order of DN200 valves?
A: Lead times vary based on order quantity and specific configurations. For standard DN200 valves in common pressure ratings, we typically maintain some stock. For larger or customized orders, production lead time is generally 4-8 weeks. We provide accurate timelines upon receipt of your detailed inquiry. -
Q: Do you offer actuated versions of these gate valves?
A: Yes, we can equip these valves with electric actuators, pneumatic actuators, or gearboxes for automated or remote operation. We can supply the complete package or just the valve ready for actuator mounting, depending on your needs. -
Q: How do I determine the correct pressure rating (PN) for my application?
A: The pressure rating should be selected based on the maximum working pressure and temperature in your system, including any potential surge pressures. PN16 is common for many water applications. Our technical team can assist you in selecting the appropriate rating based on your system parameters. -
Q: What kind of warranty do you offer on these valves?
A> Our valves come with a standard warranty against material and manufacturing defects. The specific warranty period and terms are provided with the commercial contract. Our ISO9001 quality system ensures consistent production quality to minimize issues. -
Q: Can I get a sample valve for testing before placing a bulk order?
A: Sample valves are available for evaluation, typically subject to a sample charge which may be credited against a subsequent bulk order. This allows you to verify dimensions, performance, and quality firsthand.
