As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves. Our Manual Marine Butterfly Valve with Lever Handle is engineered to meet the rigorous demands of marine and offshore applications. Designed for reliable flow control in seawater, ballast, cooling, and fire-fighting systems, this valve offers exceptional durability and ease of operation. Backed by our commitment to quality and a comprehensive 2-year warranty, this valve provides a cost-effective and dependable solution for shipbuilders, shipyards, and marine engineering projects worldwide.
The core value of this valve lies in its robust construction and user-friendly design. The lever handle allows for quick and decisive quarter-turn operation, enabling rapid opening or closing even in tight spaces onboard vessels. Manufactured with high-grade materials and subjected to stringent quality control, each valve is supplied with a Mill Test Report, providing full traceability and assurance of material integrity. This is a critical component for ensuring system safety and operational efficiency in harsh marine environments.
Key Features & Technical Advantages:
- Robust Lever Handle: Provides clear visual indication of valve position (open/closed) and allows for manual operation without additional tools. The ergonomic design reduces operator fatigue.
- Corrosion-Resistant Construction: Available in various material combinations like cast iron/SS316 disc or full stainless steel body to withstand saltwater, chemicals, and atmospheric corrosion.
- Bubble-Tight Shut-off: Features a resilient seat (EPDM/NBR/Viton options) that ensures a reliable seal, minimizing leakage and ensuring system integrity.
- Compact & Lightweight Design: The wafer or lug design requires less space and weight compared to gate valves, making it ideal for space-constrained marine installations.
- Low Maintenance: Simple design with minimal moving parts reduces the need for frequent maintenance, lowering lifecycle costs.
- Versatile Connection: Compatible with standard flanged piping systems, facilitating easy installation and replacement.

Frequently Asked Questions (FAQ)
-
Q: Is this valve suitable for seawater applications?
A: Yes, absolutely. It is specifically designed as a marine valve. We offer material options like stainless steel bodies and discs, along with seawater-resistant seat elastomers like EPDM, to ensure excellent corrosion resistance in saltwater environments. -
Q: What is included with the Mill Test Report?
A: The Mill Test Report (MTR) is a certificate from the material mill. It details the chemical composition and mechanical properties (like tensile strength, yield strength) of the metallic components (body, disc, stem) used in your specific valve batch, providing traceability and quality assurance. -
Q: Can the lever handle be locked in position?
A: Yes, the lever handle typically has holes that allow for the application of a padlock or a locking device. This is a common feature for safety isolation purposes, ensuring the valve remains in the desired open or closed position. -
Q: What is the difference between wafer and lug type connections?
A: A wafer valve is installed between two 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. Lug types are often preferred for end-of-line services or where one side may need to be disconnected. -
Q: How does the 2-year warranty work?
A: Our warranty covers defects in materials and workmanship under normal use for a period of two years from the date of shipment. Should a covered defect occur, we will repair or replace the valve at our discretion. Specific warranty terms are provided with the commercial documentation. -
Q: Are these valves approved by marine classification societies?
A: While we manufacture valves to standards commonly referenced by classification societies (like ISO, API), formal approval from specific societies (e.g., ABS, DNV, LR) is typically granted for the entire valve assembly upon project-specific testing and submission by the shipyard or engineering firm. We can provide supporting documentation (MTR, ISO9001) required for such approval processes. -
Q: What is the typical delivery lead time?
A: Lead time depends on the specific material, size, and quantity ordered. Standard configurations are often available from stock or have shorter production cycles. We provide accurate lead time estimates upon receipt of your detailed inquiry. -
Q: Can you provide valves with different seat materials?
A: Yes, we offer a selection of seat materials including EPDM for general water services, NBR for oil applications, and Viton (FKM) for higher temperature or chemical resistance. The optimal choice depends on your media temperature and chemical compatibility.
