As a dedicated manufacturer with ISO9001-certified production, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our robust Manual Marine Butterfly Valve, engineered specifically for demanding bilge line applications. Since our establishment in 2016, we have focused on delivering reliable flow control solutions for the global maritime industry, exporting to key markets across five continents. This lever-operated valve combines straightforward manual control with clear visual indication, offering shipbuilders and marine engineers a dependable, cost-effective solution for managing bilge water and other onboard fluids. Its design prioritizes ease of operation, durability in corrosive environments, and maintenance simplicity, making it an essential component for ensuring vessel safety and operational efficiency.

Core Product Features & Technical Advantages:

Lever Handle with Precise Position Indicator: The valve features a robust lever handle integrated with a clear position indicator (Open/Closed). This design allows for instant visual confirmation of the valve status, which is critical for safety procedures and efficient system management onboard ships. The lever provides excellent mechanical advantage for smooth 90-degree operation, even under moderate pressure.
Optimized for Marine Bilge Systems: Specifically constructed to handle the challenging conditions of bilge lines, which may contain oily water, sludge, and debris. The valve's disc design and seat material selection ensure reliable shut-off and minimize clogging or sticking, which is vital for effective bilge pumping and overboard discharge control.
Durable Construction & Corrosion Resistance: Manufactured from high-grade materials suitable for seawater and marine atmospheres. Common body materials include cast iron with epoxy coating, bronze, or stainless steel (304/316). The stem is typically stainless steel, and the seat is available in resilient materials like EPDM or NBR, offering good chemical resistance and long service life.
Compact & Space-Saving Wafer/Lug Design: The wafer or lug style body fits snugly between pipe flanges, resulting in a lightweight and compact installation. This is a significant advantage in the often-crowded machinery spaces and bilge areas of vessels, where space is at a premium and weight savings are beneficial.
Easy Operation & Low Maintenance: The simple quarter-turn operation requires minimal effort. The stem sealing arrangement is designed for easy adjustment or replacement if needed, reducing downtime and maintenance costs. No specialized tools are required for routine operation or basic servicing.
Versatile Pressure & Temperature Ratings: Designed to meet common marine system requirements, suitable for a range of pressures and temperatures encountered in bilge, ballast, and general service water lines.

Benefits for Your Marine Operations:

Enhanced Safety: The clear position indicator prevents accidental misoperation, ensuring bilge lines are correctly opened or closed during critical operations, contributing to overall vessel safety.
Operational Reliability: Built with marine-grade materials and robust construction to withstand vibration, shock, and corrosive elements common in shipboard environments, reducing failure rates and unscheduled repairs.
Cost-Effectiveness: As a manual valve, it requires no external power source, lowering installation and operational energy costs. Its simple design also translates to a competitive initial purchase price and low lifetime maintenance expenses.
Ease of Installation & Service: The wafer/lug design simplifies installation between existing flanges. The standardized design allows for easy parts replacement if necessary, minimizing vessel downtime in port.
Global Compliance & Support: Manufactured under an ISO9001 quality management system, our valves are designed to meet international marine standards. With annual exports valued between US$1-1.5 million and shipment capabilities from major Chinese ports like Shanghai and Guangzhou, we ensure reliable supply and support to shipyards and marine suppliers worldwide, from North America and Europe to Southeast Asia and Africa.

Frequently Asked Questions (FAQ):

Q: Is this butterfly valve suitable for seawater applications in bilge lines?
A: Yes, it is specifically designed for marine environments. We offer body materials like epoxy-coated cast iron or stainless steel (304/316) and seat materials like EPDM, which provide excellent resistance to corrosion from seawater and bilge fluids.
Q: Can the lever handle be locked in position?
A: Yes, a lockable handle option is available. This feature allows you to secure the valve in either the fully open or fully closed position, which is a useful safety and procedural measure onboard.
Q: What flange standards do your wafer/lug valves comply with?
A: Our valves are manufactured to common international standards such as ISO, DIN, JIS, and API. It is important to specify your required flange standard (e.g., PN10/16, 150LB) and facing (RF, FF) when ordering to ensure proper fit.
Q: What is the maximum pressure this valve can handle for bilge service?
A: Standard ratings are PN10 (10 bar) and PN16 (16 bar), which are typically more than sufficient for bilge pump discharge lines. Higher pressure classes may be available upon request.
Q: How do I know if the valve is fully open or closed?
A: The lever handle itself acts as a clear indicator. When the lever is parallel to the pipe, the valve is fully open. When it is perpendicular, the valve is fully closed. Additional markings are often provided on the handle or body for clarity.
Q: Are spare parts like seals or stems readily available?
A: Yes, as the manufacturer, we maintain an inventory of common spare parts. We recommend keeping a set of critical seals on board for essential valves to facilitate quick repairs if needed.
Q: Do you offer valves with extended stems for insulated pipes?
A: Yes, an extended stem option is available for applications where the valve needs to be accessible above pipe insulation. Please specify this requirement during inquiry.
Q: What is your typical lead time for orders, and which ports do you ship from?
A: Lead times vary based on order quantity and specification. We have efficient production planning and ship regularly from major ports including Shanghai, Guangzhou, Hong Kong, and Beijing, ensuring reliable delivery to global destinations.
