As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable flow control solutions for the global marine industry. Our Manual Marine Butterfly Valve with Lever Handle is engineered specifically for the demanding environment of on-deck ballast water piping systems. This valve offers a robust, cost-effective, and highly efficient method for controlling ballast water flow, ensuring operational safety and compliance with marine standards. With over eight years of manufacturing excellence and a strong export presence across continents including North America, Southeast Asia, and Europe, our products are trusted for their durability and performance in critical applications.
The core value of this valve lies in its simplicity and reliability. Designed for manual operation, it provides immediate and clear visual indication of the valve position—fully open or fully closed—through its lever handle. This is crucial for ballast water management, where precise control is needed to maintain vessel stability and trim. The valve's construction prioritizes corrosion resistance and long service life, even in the harsh saline and sun-exposed conditions of on-deck installations.
Key Product Features & Technical Advantages:
- Robust Lever Handle Design: Provides a secure grip and allows for quick, quarter-turn operation. The handle is ergonomically shaped and can be padlocked in the open or closed position for safety.
- Superior Sealing Performance: Utilizes a high-grade elastomer seat (EPDM standard, with NBR and Viton options) that ensures bubble-tight shut-off, preventing ballast water leakage which is vital for environmental protection and system efficiency.
- Corrosion-Resistant Construction: Critical components like the disc and stem are available in stainless steel (316/304) or bronze, offering excellent resistance to seawater corrosion and extending maintenance intervals.
- Compact & Lightweight Wafer/Lug Body: The wafer-style design minimizes space requirements and weight compared to gate valves, simplifying installation between pipe flanges without needing additional support.
- Low Operating Torque: The balanced disc design and low-friction bearings ensure smooth operation with minimal manual effort, even in larger sizes, reducing operator fatigue.
- Versatile Application: While ideal for ballast water control, this valve is also perfectly suited for other on-deck seawater services, fire mains, cooling water lines, and general shipboard piping.

Frequently Asked Questions (FAQ)
-
Q: Is this butterfly valve suitable for seawater applications?
A: Absolutely. The valve is specifically designed for marine environments. We offer material combinations like stainless steel discs/stems and EPDM or Viton seats that provide excellent corrosion resistance against seawater. -
Q: Can the lever handle be locked?
A: Yes. The standard lever handle is designed with a hole at the end, allowing it to be padlocked in either the fully open or fully closed position. This is a critical safety feature for ballast water systems. -
Q: What is the difference between wafer and lug type connections?
A: A wafer valve is installed between two pipe flanges using long bolts. A lug-style valve has threaded inserts (lugs) on the valve body, allowing it to be bolted directly to each flange independently, which can be beneficial for end-of-line applications or where one side needs to be disconnected. -
Q: Do you offer valves with gear operators instead of lever handles?
A: While this specific product is a manual lever handle valve, gear operators are available as a customization option for larger sizes (typically above DN300) where higher operating torque is involved. Please inquire for details. -
Q: What is the lead time for standard sizes?
A: For common sizes and standard material configurations, we typically maintain stock or can produce with a lead time of 4-6 weeks. Exact timing depends on order quantity and current production schedule. -
Q: Are your valves compliant with specific marine society approvals?
A: Our valves are manufactured to recognized international standards like ISO and API. While we hold ISO9001 for our quality system, specific class approvals from societies like DNV, ABS, or LR can be arranged upon request and may involve additional testing and documentation. -
Q: Can you provide valves with different end flanges (e.g., JIS, DIN)?
A: Yes. We can customize the flange facing dimensions and standards (such as DIN, ANSI, JIS, BS) to match your existing piping specifications. Please provide the required standard and pressure class when requesting a quote. -
Q: What is your packaging for export to prevent corrosion during sea transit?
A: We use anti-corrosion VCI (Vapor Corrosion Inhibitor) packaging. Valves are cleaned, dried, coated with rust preventive, wrapped in VCI paper, and placed in sturdy wooden cases or plywood boxes suitable for long-distance ocean freight.
