As a professional valve manufacturer with a strong export presence, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance Marine Butterfly Valve series, engineered specifically for the demanding shipbuilding industry. Since our establishment in 2016, we have dedicated ourselves to producing robust fluid control solutions that meet rigorous marine standards. Our DN50-DN600 range in 316 Stainless Steel wafer type design offers shipyards and marine equipment suppliers a reliable, corrosion-resistant, and cost-effective valve solution for various onboard systems, from ballast and bilge to cooling and fuel lines.
This valve is constructed to withstand harsh marine environments. The core advantages of this product include:
- Superior Corrosion Resistance: The body and disc are made from 316 stainless steel, which provides excellent resistance to saltwater, chemicals, and atmospheric corrosion, ensuring long service life even in offshore conditions.
- Compact & Lightweight Wafer Design: The wafer-type configuration allows for easy installation between two pipe flanges, saving significant space and weight compared to lug-type or flanged valves – a critical factor in ship design.
- Bubble-Tight Shut-off (Optional): Available with high-performance elastomer seats (like EPDM or PTFE) to achieve bubble-tight sealing, essential for critical isolation applications.
- Low Torque Operation: The streamlined disc design and precision-machined stem result in low operating torque, allowing for easier manual operation or enabling the use of smaller, more economical actuators.
- Versatile Actuation: Can be fitted with manual lever, gearbox, or various pneumatic/electric actuators based on system automation requirements and available space.
- Broad Compatibility: Designed to fit between standard ANSI, DIN, JIS, or GB flanges, making it suitable for integration into existing or new ship piping systems worldwide.

Frequently Asked Questions (FAQ):
-
Q: Is this butterfly valve suitable for seawater applications?
A: Yes, the use of 316 stainless steel provides excellent resistance to chloride-induced corrosion, making it a preferred material for handling seawater in ballast, cooling, and firefighting systems. -
Q: Can this wafer-type valve be used in a dead-end service (where pressure is applied from one side only)?
A: Standard wafer valves are generally not recommended for dead-end service. For such applications, a lug-type butterfly valve or a valve with a reinforced design should be considered. Please consult our engineers for the appropriate solution. -
Q: What is the lead time for an order of DN400 valves with pneumatic actuators?
A: Lead times vary based on order quantity and actuator specifications. Generally, for standard configurations, production takes 4-6 weeks. We provide accurate timelines upon receipt of your detailed inquiry. -
Q: Do you provide certificates for the materials?
A: Yes, material test certificates (MTC) for the 316 stainless steel can be provided upon request, which is often required for marine project documentation. -
Q: Is the valve suitable for fuel oil lines?
A: Yes, with the appropriate seat material selection (such as Viton or PTFE for wider chemical compatibility), this valve can be used for marine diesel oil (MDO) or other fuel services. The specific media and temperature must be confirmed for seat selection. -
Q: How does the gear operator differ from the lever handle?
A: A gear operator provides a mechanical advantage, significantly reducing the effort required to operate larger-sized valves (typically DN200 and above) and allows for precise flow control. A lever handle is simpler and more cost-effective for smaller valves or where quick on/off operation is sufficient. -
Q: Can you supply valves according to specific international standards like ANSI or JIS?
A: Absolutely. While our standard production often aligns with ISO/DIN, we regularly manufacture valves to meet ANSI, JIS, GB, and other regional standards. Please specify your required standard when inquiring. -
Q: What kind of packaging do you use for export to prevent damage during sea freight?
A: Each valve is individually protected with anti-corrosion coating and wrapped. They are then securely packed in wooden crates or plywood boxes suitable for long-distance ocean transport, ensuring they arrive in perfect condition.
