Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a dedicated manufacturer specializing in high-performance industrial valves for demanding global markets. With an annual export value of US$1 Million to US$1.5 Million, we have built a reputation for reliability and quality, serving clients across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, and beyond. Our DIN 3357 PN16 PN25 Ball Valve is engineered specifically for critical marine projects, offering robust construction, precise operation, and comprehensive quality assurance through a full factory testing and documentation package. This product represents our commitment to providing solutions that meet the stringent requirements of shipbuilding, offshore platforms, and marine systems.
The valve is designed to ensure safety, durability, and efficient flow control in marine environments. Key features and advantages include:
- Adherence to DIN 3357 Standard: Manufactured according to the DIN 3357 standard for flanged ball valves, ensuring compatibility with European and international piping systems commonly used in marine engineering.
- Dual Pressure Rating: Available in PN16 and PN25 pressure classes, providing flexibility for different system pressure requirements onboard vessels or offshore installations.
- Full Port Design: Features a full port (full bore) ball, minimizing flow resistance and pressure drop, which is crucial for efficient fluid transfer in marine applications.
- Robust Construction Materials: Typically constructed from carbon steel for general service, with stainless steel options available for corrosive environments. Material selection is customizable based on project specifications.
- Comprehensive Factory Testing: Each valve undergoes a rigorous testing protocol before shipment. This includes, but is not limited to:
| Hydrostatic Pressure Test | Verifies integrity under rated pressure (PN16/PN25). |
| Operation Torque Test | Ensures smooth opening and closing within specified torque limits. |
| Leakage Test | Checks for seal integrity and zero leakage from seats and body. |
| Visual & Dimension Inspection | Confirms adherence to dimensional standards and surface quality. |
The technical specifications for a standard model are outlined below. Please note, specific parameters like exact material grade, size (DN), and actuator type are customizable.

Frequently Asked Questions (FAQ)
Q1: Is this valve suitable for seawater (saltwater) applications?
A: Yes, it is designed for marine environments. For direct seawater contact, we recommend specifying stainless steel (such as 316) for the body and internals to ensure optimal corrosion resistance.
Q2: What does the "Full Factory Testing Package" include?
A: It includes hydrostatic pressure testing, operational torque testing, leakage testing, and final visual/dimensional inspection. Detailed test reports for each valve are provided as part of the documentation.
Q3: Can this valve be fitted with an actuator for remote operation?
A: Absolutely. The valve design accommodates the mounting of pneumatic, hydraulic, or electric actuators. Actuator type and specifications can be customized upon request.
Q4: Are the flanges compatible with ANSI/ASME standards?
A: The valve is manufactured to DIN flange dimensions as per DIN 3357. For projects requiring ANSI flange compatibility, please inquire as we may offer adapted versions or provide conversion information.
Q5: What is the typical delivery time for these valves?
A: Delivery time depends on the order quantity, size, and material specifications. Standard sizes and materials typically have shorter lead times. We provide estimated timelines upon quotation.
Q6: Does the documentation package include material traceability certificates?
A: Yes, for critical applications, material certificates (e.g., for stainless steel grades) can be provided as part of the documentation package to support quality audits.
Q7: What is the difference between PN16 and PN25 ratings?
A: PN16 indicates a nominal pressure rating of 16 bar, while PN25 indicates 25 bar. The selection depends on the maximum operating pressure in your marine system. Both are available.
Q8: Can you provide custom painting or coating for the valve exterior?
A: Yes, exterior coatings or specific paint schemes (e.g., for corrosion protection or color coding) are customizable based on project requirements.
