As a dedicated manufacturer with ISO9001-certified processes since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in engineering robust fluid control solutions for demanding global industries. Our Chemical Tanker Butterfly Valve is engineered to address the critical challenges of handling aggressive and hazardous chemicals in transportation and processing. Featuring a PTFE-lined body and a fire-safe design certified per API 609, this valve offers unparalleled corrosion resistance and failsafe performance, ensuring operational integrity and environmental safety for tanker fleets and chemical plants worldwide.

This valve is designed to provide secure, leak-tight shutoff and precise flow control for a wide spectrum of corrosive media, including acids, alkalis, solvents, and other aggressive chemicals commonly transported via tankers. Its construction prioritizes durability and safety, making it a reliable component in critical piping systems.

Core Features & Technical Advantages:

Superior Corrosion Resistance: The valve body is lined with high-grade PTFE (Polytetrafluoroethylene), creating an inert barrier that is highly resistant to almost all industrial chemicals, preventing contamination and extending service life.
API 609 Fire-Safe Design: In the event of a fire, the valve's fire-safe design ensures it maintains a seal, preventing the escalation of a hazardous situation. This is a critical safety feature for chemical tankers and processing facilities.
Broad Size Compatibility: Available in sizes from DN80 to DN200 (3" to 8"), providing versatile options for various pipeline configurations on tankers and within plants.
Low Maintenance & Easy Operation: The simple butterfly disc design ensures quick quarter-turn operation with low torque. The PTFE lining minimizes sticking or binding, reducing maintenance frequency and effort.
Robust Construction: Typically constructed with a carbon steel or stainless steel body (lined with PTFE) and a corrosion-resistant disc (often 316SS or higher alloy), ensuring structural integrity under pressure and harsh conditions.
Bubble-Tight Shutoff: The resilient PTFE seat provides excellent sealing capabilities, achieving bubble-tight shutoff to prevent product loss and ensure accurate batch control.

Benefits for Your Operations:

Enhanced Safety: The API 609 fire-safe certification provides critical protection, mitigating risks in fire scenarios, which is paramount for chemical logistics and storage.
Cost-Effective Solution: Compared to solid alloy valves, PTFE-lined butterfly valves offer excellent chemical resistance at a more economical price point, reducing capital expenditure.
Reduced Downtime: The reliable design and corrosion-resistant materials minimize failures, leading to fewer unplanned shutdowns and maintenance interventions.
Compliance Ready: Adhering to recognized industry standards like API 609 helps ensure your operations meet stringent safety and environmental regulations.
Global Supply Chain Support: With annual exports valued between US$1-1.5 million and shipments from major ports like Shanghai, Guangzhou, Hong Kong, and Beijing, we ensure timely delivery to your operations across North America, South America, Europe, Asia, Africa, and Oceania.

Frequently Asked Questions (FAQ):

Q: What is the primary advantage of a PTFE-lined valve for chemical service?
A: PTFE is chemically inert and offers exceptional resistance to a vast range of corrosive substances, including strong acids and bases. The lining protects the valve body from corrosion, preventing product contamination and extending the valve's lifespan significantly compared to unlined carbon steel valves.
Q: Why is the API 609 fire-safe designation important for a tanker valve?
A: API 609 specifies requirements for fire-safe testing of valves. In a fire, the valve's sealing elements may be compromised. A fire-safe design ensures the valve can still maintain a seal (or a specified leakage rate) under fire conditions, preventing the uncontrolled release of hazardous chemicals, which is critical for safety on tankers and in processing plants.
Q: Can this valve be automated?
A: Yes. The valve is designed to be compatible with various actuators. We can supply the valve with a pneumatic actuator (single or double-acting) or an electric actuator as an optional configuration to suit your automated control system needs.
Q: What are the typical pressure ratings for these valves in DN80-DN200 sizes?
A: Standard pressure ratings are typically PN10 (10 bar) or PN16 (16 bar), corresponding to common industrial and tanker piping system requirements. Higher pressure ratings may be available upon request for specific applications.
Q: Is the PTFE lining suitable for all chemicals?
A: While PTFE is resistant to nearly all industrial chemicals, its performance can be affected by certain media at extreme temperatures or pressures, and by some specific fluorinated compounds. It is always recommended to confirm chemical compatibility for your specific service conditions.
Q: What end connection types are available?
A: The valves are typically available in wafer style (for installation between two flanges with through-bolts) or lug style (where the valve has threaded inserts, allowing it to be bolted to a single flange, useful for end-of-line service). The choice depends on your piping layout.
Q: Do you provide documentation like test reports and material certificates?
A: As an ISO9001-certified manufacturer, we can provide standard documentation including material test reports (MTR) and factory acceptance test reports. Specific certifications like fire test reports per API 609 are available upon request.
Q: What is your lead time for an order of DN150 valves?
A: Lead times vary based on order quantity, configuration (manual vs. actuated), and current production schedule. Generally, for standard configurations, we aim for efficient production and shipment. Please contact us with your specific requirements for an accurate timeline.
