As a leading manufacturer, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our specialized Marine Butterfly Valve, engineered specifically for the demanding environments of desulfurization tower systems. With a commitment to quality since 2016 and ISO9001-certified production, we design valves that deliver exceptional reliability, precise flow control, and long-term durability in critical marine applications. Our product combines robust construction with extended warranty options and dedicated technical support, offering a complete solution for your flue gas desulfurization (FGD) needs. We understand the high-stakes nature of marine operations, and our valve is built to withstand corrosive media, high temperatures, and continuous service, ensuring your system's efficiency and compliance.
This marine butterfly valve is a cornerstone for effective and safe desulfurization processes. It features a compact, lightweight design that simplifies installation and maintenance in the often space-constrained areas of marine vessels and offshore platforms. The disc design ensures minimal pressure drop and efficient shut-off, crucial for optimizing the scrubbing process. Key product highlights include:
- Superior Corrosion Resistance: Constructed from materials like duplex steel and lined with high-performance polymers to resist acidic and abrasive slurries common in FGD systems.
- Bubble-Tight Sealing: Advanced seat designs, including resilient PTFE or metal-seated options, provide reliable, leak-proof sealing even after prolonged cycling.
- Versatile Actuation: Available with manual levers, gear operators, or automated pneumatic/electric actuators for remote or local control integration.
- Robust Shaft Connection: A secure, anti-blowout shaft design guarantees operational safety and prevents failure under high torque conditions.
- Extended Service Life: Engineered for low maintenance, with components designed to resist wear from particulate matter in the flue gas stream.

Frequently Asked Questions (FAQ)
Q1: Is this butterfly valve suitable for handling seawater in a scrubber system?
A1: Yes, it is specifically designed for marine desulfurization applications. We offer material combinations, such as duplex stainless steel body with corrosion-resistant linings, that provide excellent resistance to both the acidic scrubbing slurry and seawater used in the process.
Q2: What does the "extended warranty" typically cover and for how long?
A2: The extended warranty goes beyond standard terms, often covering defects in materials and workmanship for a longer period. Specific duration and coverage details are provided upon request and are tailored based on the valve model and application conditions.
Q3: Can you provide valves with specific face-to-face dimensions or flange standards?
A3: Absolutely. We offer customization to meet various international standards (ANSI, DIN, JIS, etc.) and can accommodate non-standard face-to-face dimensions upon request to ensure compatibility with your existing piping.
Q4: What types of actuators are compatible with this valve?
A4: The valve is designed to be compatible with a wide range of actuators. We can supply it as a manual unit (lever or gear) or pre-assembled with pneumatic (double-acting or spring-return) or electric actuators from reputable brands, based on your control system requirements.
Q5: How do I select the appropriate seat material for my FGD application?
A5: Seat selection depends on temperature, chemical composition of the slurry, and presence of abrasives. PTFE is common for general service, EPDM for wider temperature ranges, and metal seats for high-temperature or abrasive services. Our technical team can assist you in making the optimal choice.
Q6: Do you offer technical documentation and installation manuals?
A6: Yes, comprehensive documentation, including detailed datasheets, material certifications, installation and maintenance manuals, is provided with every shipment to ensure correct and safe valve operation.
Q7: What is your lead time for standard and customized orders?
A7: Lead times vary based on order quantity, size, and customization level. Standard sizes and materials typically have shorter lead times. We provide accurate delivery schedules upon order confirmation to help you plan your project timeline.
Q8: How does your technical support work after the sale?
A8: Our support includes pre-sale consultation, installation guidance, operational troubleshooting, and a reliable supply of genuine spare parts. You can contact our dedicated support team via email or phone for prompt assistance.
