As a dedicated manufacturer with a strong focus on industrial fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our specialized Marine Ball Valve engineered specifically for demanding Flue Gas Desulfurization (FGD) tower applications. Since our establishment in 2016, we have committed to producing valves that withstand the harsh, corrosive environments found in marine and power generation scrubber systems. Our valves are designed to offer reliable shut-off and control in critical processes where failure is not an option, ensuring the continuous and efficient operation of your environmental control systems. This product represents our deep understanding of the specific challenges posed by slurry, acidic condensates, and abrasive particulates in FGD loops.
Our Marine Ball Valve for Desulfurization Towers is built from the ground up to combat the aggressive conditions within FGD systems. The valve features a robust construction with materials selected for superior corrosion resistance against sulfur compounds, chlorides, and other acidic by-products. A key design focus is on preventing internal buildup and ensuring smooth operation even after prolonged exposure to scaling media. The sealing system is engineered for exceptional performance, minimizing fugitive emissions and maintaining system integrity under varying pressure and temperature cycles typical of scrubber operation.
Core Technical Features & Advantages:
- Corrosion-Resistant Material Selection: We offer body and trim materials including CF8M (316 Stainless Steel), Duplex Stainless Steels, and specially coated carbon steels to match the specific corrosivity of your flue gas desulfurization process stream, significantly extending service life.
- Enhanced Seat & Seal Design: Utilizing advanced polymers like reinforced PTFE or metal seats, the valve ensures bubble-tight shut-off against abrasive gypsum slurries and acidic condensates, reducing maintenance frequency and downtime.
- Full Port or Standard Port Design: Available in full port (full bore) configurations to minimize pressure drop across the valve, which is crucial for slurry handling, or standard port for general service, providing flexibility for different points in the FGD circuit.
- Extended Stem & Robust Actuation: The stem is designed with extended bonnets or standard lengths suitable for insulation. It interfaces seamlessly with manual levers, gear operators, or automated actuators (pneumatic/electric) for remote operation in hard-to-reach scrubber locations.
- Anti-Static & Fire-Safe Design (Optional): Features such as anti-static devices and fire-safe designs per API 607/API 6FA standards are available to enhance safety in critical hydrocarbon processing applications integrated with FGD.
Detailed Specifications & Configurations:
| Parameter | Specification / Option |
| Design Standard | API 6D, ASME B16.34, ISO 17292 |
| Face-to-Face | ASME B16.10, DIN 3202 |
| Flange Connection | ASME B16.5 (RF, RTJ), DIN, JIS, GB Standards |

Benefits for Your FGD Operation:
- Maximized System Uptime: Dependable performance reduces unplanned shutdowns for valve repair or replacement, supporting continuous compliance with emissions regulations.
- Reduced Total Cost of Ownership: The use of durable materials and optimized design lowers long-term costs associated with maintenance, parts inventory, and labor.
- Operational Safety & Environmental Compliance: Reliable sealing helps contain process media, protecting personnel and preventing environmental releases, which is paramount in scrubber systems.
- Design Flexibility: With a wide range of sizes, pressure ratings, materials, and actuation options, the valve can be tailored to fit precisely into new projects or retrofit existing FGD infrastructure.

Frequently Asked Questions (FAQ):
Q1: What makes this ball valve suitable for "marine" and FGD service compared to a standard ball valve?
A1: This valve incorporates specific material grades with enhanced corrosion resistance (e.g., higher molybdenum content in stainless steels), specialized seat materials resistant to acidic slurry, and often features like extended bonnets for insulation. It is designed and tested with the chemical and physical challenges of scrubber systems and offshore/marine atmospheres in mind.
Q2: Can you provide valves for both the absorber loop and the slurry handling sections of an FGD system?
A2: Yes. We can recommend appropriate material and trim combinations based on the specific service conditions—such as different pH levels, chloride content, and abrasiveness—in various parts of your FGD system, from inlet quenchers to gypsum dewatering.
Q3: Are your valves compliant with international standards for shipboard use or offshore platforms?
A3: Our valves are manufactured to common industry standards like API, ASME, and ISO. For specific marine classification society approvals (like ABS, DNV, LR), please inquire during the quotation process as these often require project-specific certification.
Q4: What types of actuation do you offer, and can you supply the complete package?
A4: We offer manual operation (lever or gear), as well as pneumatic (double-acting or spring-return) and electric actuation. We can supply the valve as a standalone unit or as a complete assembled package with your preferred actuator, limit switches, and solenoid valves.
Q5: What is your lead time for standard and customized orders?
A5: Lead times vary based on size, material, and configuration. Standard materials and sizes typically have shorter lead times. We provide estimated schedules upon receipt of detailed specifications and work to meet project timelines.
Q6: Do you offer technical support for valve selection and sizing?
A6> Absolutely. Our engineering team can assist with selection based on your process data (fluid, pressure, temperature, flow rate) to ensure optimal valve performance and longevity in your specific FGD application.
Q7: How do you ensure quality control during manufacturing?
A7> Our ISO9001 certification mandates a strict quality control process. This includes material certification, in-process inspections, and final testing (shell test, seat test, and functional test) according to international standards before shipment.
Q8: What are the packaging and shipping terms?
A8> Valves are typically packaged in wooden cases or crates for export protection. We ship worldwide from major Chinese ports (Shanghai, Guangzhou, Hong Kong) under standard Incoterms like FOB, CIF, or CFR, tailored to your needs.
