As a leading manufacturer with ISO 9001 certified production, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in engineering robust fluid control solutions for demanding maritime applications. Our Marine Desulfurization Tower Butterfly Valve is meticulously designed to meet the rigorous challenges of seawater-scrubbed flue gas systems, offering unparalleled reliability and longevity in corrosive environments. With extensive experience supplying to global markets from North America to Southeast Asia, we understand the critical need for valves that ensure operational continuity and environmental compliance. This valve represents our commitment to providing high-performance, durable components that protect your investment and optimize your desulfurization processes.
Engineered for resilience in the harsh conditions of marine exhaust gas cleaning, our butterfly valve boasts several key features and advantages:
- Superior Corrosion Resistance: Constructed from advanced alloys such as Duplex or Super Duplex stainless steel, the valve body, disc, and stem are specifically selected to withstand prolonged exposure to chlorides, sulfides, and other aggressive chemicals present in seawater-scrubbed flue gas.
- Bubble-Tight Shut-off: Available with a range of seat materials including resilient PTFE or EPDM for standard duties and metal seats for higher temperature applications, ensuring zero leakage and maximum process efficiency.
- Robust & Low-Maintenance Design: The streamlined disc design minimizes pressure drop and turbulence. The stem is securely sealed with multiple sealing points to prevent media ingress, reducing maintenance frequency and total cost of ownership.
- Versatile Actuation Options: The valve can be equipped with manual gear operators, electric actuators, or pneumatic actuators, allowing for seamless integration into automated shipboard control systems or manual override capability as required.

Frequently Asked Questions (FAQ)
-
Q: What makes this butterfly valve suitable for seawater-scrubbed FGD systems?
A: The valve is constructed from high-grade corrosion-resistant alloys like Duplex stainless steel, specifically chosen to withstand the highly corrosive combination of seawater, sulfur oxides, and other flue gas constituents, ensuring long-term integrity. -
Q: Can this valve be used with other scrubber media besides seawater?
A: While optimized for seawater, the material selection and design also make it suitable for other alkaline scrubber solutions, such as caustic soda, used in closed-loop or hybrid systems. Please consult our engineers for your specific media. -
Q: What actuation options are available?
A: We offer a full range: manual gear operation for local control, electric actuators for precise automated control, and pneumatic actuators for rapid response. The choice depends on your system's automation level and power availability. -
Q: Do you provide valves with specific international flange standards?
A: Yes. We routinely manufacture valves with ASME/ANSI, DIN, JIS, and other common flange standards to match existing piping. Please specify your required standard and pressure class when inquiring. -
Q: What is the typical delivery lead time?
A: Lead times vary based on size, material, and actuation. Standard configurations typically ship within 4-6 weeks. We maintain efficient logistics through ports like Shanghai and Hong Kong to expedite global delivery. -
Q: How does the valve ensure bubble-tight shut-off in such a demanding service?
A: The combination of a precision-machined disc, a resilient or metal seat designed for high sealing force, and a robust stem sealing system ensures minimal leakage, meeting or exceeding industry standards like ISO 5208 for leakage rates. -
Q: Are custom sizes or special coatings available?
A: Absolutely. We specialize in customization. Valves outside the standard size range, with special internal/external coatings for enhanced corrosion protection, or with unique material combinations can be engineered to meet your project's exact needs. -
Q: What after-sales support do you provide?
A: We provide comprehensive technical documentation, installation guidance, and responsive customer service. Our team is available to assist with troubleshooting and can supply spare parts like seals and seats to minimize operational downtime.
