As a dedicated manufacturer since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd specializes in high-quality marine fluid control components. Our Marine Self Closing Valve For Ship Fuel Oil System (DN15, PN16) is designed to automatically release and close, ensuring maximum safety and operational reliability in ship fuel handling. Built with precision engineering and ISO9001-certified quality, this valve offers a robust solution for preventing fuel leaks and fire hazards in marine environments.
The valve's automatic release mechanism triggers instant closure when abnormal conditions are detected, such as excessive flow or pressure drop. This feature is critical for protecting crew, cargo, and equipment. Below we detail the key features, technical specifications, and benefits that make this valve a trusted choice for vessel operators worldwide.
- Automatic Release & Closing: Built-in spring-loaded mechanism ensures positive shut-off upon loss of pressure or manual activation, minimizing spill risk.
- Durable Material Options: Available in cast steel or bronze — both materials offer excellent corrosion resistance against marine fuel oil and seawater.
- Compact DN15 Design: Fits into tight piping layouts, ideal for space-constrained engine rooms and fuel supply lines.
- PN16 Pressure Rating: Suitable for low to medium pressure fuel systems (up to 16 bar), commonly used in auxiliary and main engine fuel circuits.
- Versatile Connections: Choose flanged or threaded ends to match existing shipboard piping standards.
- Low Maintenance: Simple internal structure with few moving parts reduces wear and extends service life.
- Customizable Color & Finish: Blue coating is standard; other colors and surface treatments are available upon request.
