As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves for global markets. Our DN15-DN100 Marine Ball Valve, engineered to the CB/T3191-92 standard, is a robust and reliable solution designed specifically for demanding marine and industrial applications. This valve combines precision threading, a durable pressure rating, and a compact design to ensure secure flow control in critical piping systems.
This valve is engineered for optimal performance and longevity. Key features and advantages include:
- Versatile Thread Compatibility: Equipped with male BSP (British Standard Pipe) or NPT (National Pipe Taper) threads, providing excellent adaptability for international pipeline connections, reducing the need for adapters.
- Robust Pressure Handling: Rated for PN16 pressure, ensuring reliable operation under standard industrial and marine system pressures, enhancing system safety.
- Superior Sealing Performance: Typically features PTFE (Teflon) seats and seals, offering excellent chemical resistance and low friction for smooth, bubble-tight shut-off, minimizing leakage risks.
- Compact & Space-Saving Design: The full port or standard port ball valve design offers minimal flow restriction and a compact form factor, ideal for space-constrained engine rooms and equipment panels.
- Corrosion Resistance: The valve body, commonly manufactured from bronze or brass, provides excellent resistance to saltwater corrosion, a critical requirement for marine environments.
- Easy Operation & Maintenance: The quarter-turn lever handle allows for quick and easy open/close operation. The simple design facilitates easy inspection and maintenance, reducing downtime.

Frequently Asked Questions (FAQ)
-
Q: What is the main difference between BSP and NPT threads on this valve?
A: BSP (British Standard Pipe) threads are parallel, while NPT (National Pipe Taper) threads are tapered. The sealing mechanism differs: BSP often uses a washer/seal on the parallel threads, while NPT relies on thread deformation for sealing. It's crucial to specify which standard you require to ensure a proper fit. -
Q: Is this valve suitable for seawater applications?
A: Yes, it is designed as a marine ball valve. The common body materials like bronze and brass offer good corrosion resistance against seawater. However, for specific fluid compatibility, please confirm the exact material grade with us. -
Q: What does the pressure rating PN16 mean?
A: PN16 indicates a nominal pressure rating of 16 bar at room temperature (20°C). This is a standard metric rating equivalent to approximately 232 PSI, suitable for many marine and industrial water, oil, and air systems. -
Q: Can you provide valves with female threads or other connection types?
A: Yes, as a manufacturer, we offer customization. Female threaded ends, socket weld ends, or flanged ends are often available upon request. Please inquire with your specific needs. -
Q: What is the significance of the CB/T3191-92 standard?
A: CB/T3191-92 is a Chinese professional standard for marine forged copper alloy globe valves and check valves. Ball valves designed to this standard generally adhere to stringent requirements for materials, dimensions, pressure testing, and performance suitable for shipboard use. -
Q: What is the typical lead time for an order?
A: Lead time depends on order quantity and specifications. For standard DN15-DN100 male thread valves, we often have stock or short production cycles. We provide accurate lead times upon receipt of your inquiry. -
Q: Do you offer any other pressure ratings besides PN16?
A: Yes, we produce valves with various pressure ratings such as PN10, PN25, PN40, and Class 150/300. Please specify your required pressure class when contacting us. -
Q: What kind of packaging do you use for export?
A: We use standard export packaging: each valve is individually wrapped, packed in carton boxes, and then placed on wooden pallets for sea freight, ensuring safe delivery to our global clients.
