As a professional valve manufacturer with ISO 9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our DN200 Full Bore Ball Valve, engineered in strict compliance with the DIN 3357 standard. Designed for demanding industrial applications, this flanged connection valve offers superior flow capacity and reliable shut-off for critical pipeline systems. Our commitment to precision manufacturing since 2016 ensures that every valve delivers consistent performance and durability, meeting the rigorous requirements of global markets from North America and Europe to Southeast Asia and Africa.
This robust ball valve is engineered to provide a perfect balance of performance, reliability, and ease of maintenance. The full bore design ensures minimal pressure drop across the valve, making it ideal for applications where flow efficiency is paramount. The flanged ends, manufactured to standard dimensions, allow for secure and leak-free connection to existing piping networks, simplifying installation and replacement procedures.
Key Features and Technical Advantages:
- Optimized Flow Path: The full port (full bore) design provides a flow area equal to the pipeline's inner diameter, virtually eliminating flow restriction and pressure loss. This is crucial for pumping systems to reduce energy consumption and maintain system pressure.
- Robust Construction & Standards Compliance: Manufactured in accordance with DIN 3357, this valve guarantees dimensional interchangeability and performance reliability. The sturdy construction can withstand high cycle operations and harsh industrial environments.
- Superior Sealing Performance: Utilizing advanced seat materials like PTFE or reinforced PTFE, the valve ensures bubble-tight sealing in both directions. The design minimizes wear on the seats, extending service life even with frequent operation.
- Versatile Operation and Actuation: Available with a standard lever for manual operation. For larger systems or automated control, options include gear operators or pneumatic actuators, providing flexibility for various control schemes.
- Easy Maintenance & Installation: The top-entry or side-entry design (depending on model) allows for inline maintenance. Seats and seals can be inspected or replaced without removing the valve body from the pipeline, significantly reducing downtime.
- Wide Material and Pressure Compatibility: The valve body is typically offered in carbon steel (WCB) or stainless steel (CF8/CF8M). It is designed for pressure ratings such as PN16, PN25, or PN40, catering to a broad spectrum of system requirements.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a full bore ball valve compared to a reduced bore valve?
A: A full bore valve has an internal diameter matching the pipeline, resulting in negligible pressure drop. This is essential for applications like pigging, slurry transport, or where minimizing flow resistance is critical for system efficiency.
Q2: Is this valve suitable for throttling service?
A: While ball valves can be used for moderate throttling, they are primarily designed for on/off service. For precise flow control, a different valve type like a control valve is recommended. Extended use in a partially open position may accelerate seat wear.
Q3: Can you provide valves with different flange face types or standards, like ASME B16.5?
A: Yes. While compliant with DIN 3357/EN 1092-1, we can manufacture valves with ASME B16.5 flanges (RF, RTJ face) or other standards upon request. Please specify your required flange standard and facing in your inquiry.
Q4: What are the available options for valve actuation?
A: We offer a range of actuation solutions: manual lever, manual gearbox (for high torque), and automated actuators (pneumatic double-acting/single-acting, electric, hydraulic). Actuators can be fitted with limit switches, positioners, and other accessories.
Q5: What is the typical lead time for an order of DN200 valves?
A: Lead time depends on the specific configuration, material, and order quantity. For standard carbon steel valves with PTFE seats, production is generally faster. We provide accurate lead time estimates with every quotation to help you plan.
Q6: Do you offer any special coatings or treatments for corrosive environments?
A: Absolutely. Beyond standard materials like stainless steel, we can apply epoxy coatings, galvanization, or other surface treatments to the valve exterior for enhanced corrosion protection. Internally, special hard coatings on the ball are also available.
Q7: How do you ensure the quality and leakage rate of the valves?
A: Every valve undergoes rigorous testing before shipment. This includes shell strength tests, seat leakage tests (typically per API 598 or equivalent standards), and operational tests. Our ISO 9001 certification underpins this consistent quality control process.
Q8: Can you provide documentation like material test certificates and inspection reports?
A: Yes, we provide full documentation packages, which can include Material Test Certificates (MTC/CMTR), factory test reports, certificates of conformity, and operational manuals. These are available upon request.
