As a leading manufacturer with a strong commitment to quality and precision, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our DIN 3357 Ball Valve, engineered from 304 Stainless Steel. Established in 2016 and backed by ISO9001 certification, our focus is on delivering reliable fluid control solutions that enhance operational efficiency for our global clientele across North America, Europe, Asia, and beyond. This valve is specifically designed with a full port configuration to minimize pressure drop, ensuring smooth and efficient flow in your critical piping systems. We understand that in industrial applications, performance and durability are non-negotiable, which is why this valve is crafted to meet rigorous standards.
The core value of this product lies in its ability to provide a superior sealing solution with minimal flow resistance. The full port design, a key feature, ensures the bore diameter is nearly equal to the pipeline's inner diameter, drastically reducing turbulence and pressure loss. This is particularly advantageous for systems where maintaining consistent pressure and flow rate is essential. Constructed from high-grade 304 stainless steel, the valve offers excellent resistance to corrosion, oxidation, and a wide range of media, making it suitable for demanding environments in chemical processing, water treatment, food and beverage, and general industrial services.
Detailed Features and Technical Advantages:
- Optimized Full Port Design: The internal flow path is maximized to match the pipeline ID, which significantly lowers the pressure drop across the valve. This design translates to energy savings for pumping systems and allows for pigging or cleaning of the pipeline without removal.
- Robust 304 Stainless Steel Construction: Provides outstanding mechanical strength and corrosion resistance against water, steam, oil, gas, and many mild corrosive chemicals, ensuring a long service life even in harsh conditions.
- DIN 3357 Compliance: Manufactured in accordance with the DIN 3357 standard for flanged ball valves, ensuring dimensional interchangeability, reliable performance, and compatibility with other DIN-standard pipeline components in European and international markets.
- Bubble-Tight Sealing: Equipped with advanced PTFE or reinforced PTFE seats, the valve offers excellent sealing performance, achieving bubble-tight shut-off and minimizing leakage risks.
- Easy Operation and Low Maintenance: Features a standard lever handle for quick 90-degree operation. For larger sizes or higher torque requirements, a gear operator is available. The simple design ensures easy maintenance and reduces downtime.
- Versatile Application Range: Suitable for on/off and throttling service in a wide spectrum of industries including, but not limited to, petrochemical, pharmaceutical, power generation, and HVAC systems.
The following table outlines key technical specifications for common sizes:
| Nominal Diameter (DN) | Pressure Rating (PN) | Temperature Range | End Connection |
| DN15 - DN300 | PN16, PN25, PN40 | -20°C to +180°C (with PTFE seats) | Flanged (DIN 2501) |
| DN350 - DN500 | PN16 | -20°C to +180°C (with PTFE seats) | Flanged (DIN 2501) |
Benefits for Your Business:
- Enhanced System Efficiency: The low-pressure drop characteristic reduces pump energy consumption, leading to lower operational costs over time.
- Reduced Total Cost of Ownership: The durability of 304 stainless steel and reliable sealing components minimize the frequency of repairs and replacements.
- Global Compatibility: Adherence to DIN standards facilitates seamless integration into existing international projects and simplifies procurement of spare parts.
- Operational Safety: The robust construction and reliable shut-off capability contribute to a safer working environment by preventing leaks and potential process interruptions.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a full port ball valve over a standard port one?
A: A full port (or full bore) ball valve has an internal bore diameter approximately equal to the pipeline's inner diameter. This design minimizes flow restriction, resulting in a very low pressure drop, which is crucial for maintaining system pressure and efficiency, especially in applications requiring minimal flow resistance or pipeline pigging. -
Q: Is this valve suitable for use with corrosive chemicals?
A: The 304 stainless steel construction offers good resistance to a wide range of mildly corrosive media, including water, steam, many oils, and gases. However, for highly corrosive or specialized chemicals, we recommend consulting our technical team to confirm material compatibility or discuss alternative materials like 316 stainless steel. -
Q: What does DIN 3357 refer to?
A: DIN 3357 is a German industrial standard that specifies the design, dimensions, pressure-temperature ratings, and testing requirements for flanged ball valves. Valves manufactured to this standard ensure dimensional consistency and performance reliability, facilitating their use in systems designed to European norms. -
Q: Can this valve be operated automatically?
A: Yes. While it is typically supplied with a manual lever or gear operator, this ball valve can be easily fitted with an electric or pneumatic actuator for automated process control. Actuator mounting kits are available upon request. -
Q: What is the lead time for an order?
A: Lead times vary based on order quantity, valve size, and specific configuration. Standard sizes are often available from stock or have shorter production cycles. We provide estimated lead times with every quotation to help you plan your project schedule effectively. -
Q: Do you provide custom markings or packaging?
A: Yes, we offer customization options for valve markings, such as logos or specific identification tags, as well as specialized export packaging to ensure safe transit. Please discuss your requirements during the inquiry stage. -
Q: What pressure classes (PN) are available?
A> This valve series is commonly available in PN16, PN25, and PN40 pressure ratings. The specific rating for a given size can be confirmed in our detailed technical datasheet. -
Q: How do I determine the correct valve size for my application?
A: The correct size is primarily determined by your pipeline's nominal diameter (DN). We also recommend considering the required pressure rating (PN), media type, temperature, and flow characteristics. Our technical support team can assist you in selecting the most suitable valve based on your application parameters.
