As a specialized manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. leverages its expertise since 2016 to produce robust industrial valves for global markets. Our Full Port DIN 3357 Marine Ball Valve with Flanged Ends represents a core product engineered for demanding marine and offshore applications. This valve combines the high-flow efficiency of a full port design with the reliability of DIN standards and the critical safety option of fire-safe construction, offering a dependable solution for fluid control systems where performance and safety are paramount.

This valve is designed to meet the stringent requirements of shipbuilding, offshore platforms, and port infrastructure. Its flanged ends ensure secure and standardized connections, facilitating easy installation and maintenance within piping networks. The optional fire-safe design provides an extra layer of protection, making it suitable for applications handling flammable media or operating in high-risk environments.

Key Features and Technical Specifications:

Full Port Design: Provides minimal flow resistance, offering a flow capacity nearly equal to the pipeline itself, which is crucial for systems requiring high throughput and efficiency.
DIN 3357 F4 Standard Compliance: Manufactured according to the DIN 3357 F4 standard for flanged ball valves, ensuring dimensional accuracy, material quality, and performance consistency recognized in European and international markets.
Robust Construction: Available in various body materials such as cast steel, stainless steel (304/316), and duplex steel to withstand corrosive marine environments, high pressures, and mechanical stress.
Fire-Safe Design Option: When specified, the valve incorporates features such as special seat materials (e.g., graphite) and a design that maintains sealing integrity even under exposure to high temperatures, helping to prevent leakage in fire scenarios.
Versatile Operation: Can be equipped with a manual lever for direct operation, a gearbox for high-torque applications, or automated with pneumatic (or electric) actuators for remote control and integration into automated systems.
Sealing Reliability: Utilizes PTFE, reinforced PTFE, or metal seats depending on the service conditions, ensuring tight shut-off and long service life across a wide temperature range.

Primary Technical Parameters:

Parameter	Typical Range / Specification
Size (DN/NPS)	DN15 - DN300 (1/2" - 12")
Pressure Rating (PN)	PN16, PN25, PN40
Temperature Range	-20°C to +200°C (standard); up to +400°C with special materials/fire-safe option
Flange Standard	DIN EN 1092-1 (PN series), ANSI B16.5 (optional)
Fire Safe Test Standard	API 607, API 6FA, ISO 10497 (optional)

Benefits for Your Project:

Enhanced System Efficiency: The full port design minimizes pressure drop, allowing pumps and systems to operate more efficiently, potentially reducing energy consumption.
Simplified Installation & Maintenance: Flanged ends allow for straightforward bolting to pipeline flanges, enabling easier installation, removal for service, and replacement.
Increased Safety & Compliance: The optional fire-safe design helps projects meet stricter safety regulations for hazardous areas, protecting assets and personnel.
Long-Term Durability: Constructed from selected materials and compliant with DIN standards, the valve offers reliable performance and extended service life in harsh marine conditions, reducing maintenance frequency and replacement costs.
Global Compatibility: Adherence to DIN standards and availability with optional ANSI flanges make the valve suitable for integration into international projects across our main markets, including North America, Europe, Asia, and beyond.

Frequently Asked Questions (FAQ)

What does "Full Port" mean in a ball valve?
A Full Port (or Full Bore) ball valve has an internal bore diameter that is approximately the same as the pipeline's inner diameter. This design minimizes flow restriction and pressure drop, making it ideal for applications where high flow capacity or pigging (cleaning) of the line is required.
Is the DIN 3357 standard specific to certain regions?
The DIN 3357 standard is a German industrial norm widely recognized and used internationally, particularly in Europe and many global projects. It specifies requirements for flanged ball valves, ensuring dimensional interchangeability, material grades, and pressure-temperature ratings.
How does the optional "Fire-Safe Design" work?
When ordered with the fire-safe option, the valve incorporates design features and materials (like graphite seats) that can maintain a seal and prevent leakage even after exposure to high temperatures, as tested according to standards like API 607. This is critical for safety in applications involving flammable fluids.
Can this valve be used with ANSI flanged piping systems?
Yes. While the standard flange is per DIN EN 1092-1 (PN series), valves can be supplied with ANSI B16.5 flanges as an option upon request to match your specific piping standards.
What are the typical materials available for the valve body?
Common body materials include Cast Steel (WCB), Stainless Steel (304, 316), and Duplex Stainless Steel. The choice depends on the fluid media, corrosion requirements, and pressure-temperature conditions of your application.
Is the valve suitable for automated control systems?
Absolutely. The valve can be fitted with various actuators – pneumatic, electric, or hydraulic – for integration into automated or remotely controlled systems. Actuator selection is customizable based on your operational needs.
What is the typical delivery time for this product?
Delivery time depends on size, material, and optional features (like fire-safe). Standard configurations often have shorter lead times. Please inquire with us for a specific schedule based on your order requirements.
Do you provide test reports or certification for the valves?
We provide standard manufacturing test reports. For valves with the fire-safe option, relevant fire test certification reports from recognized laboratories can be supplied upon request.
