Standards ISO 9001 Certified Manufacturing

As a leading manufacturer with ISO 9001 certified processes, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-performance fluid control solutions for demanding industrial applications. Our Direct Replacement PTFE Lined Butterfly Valve is engineered for reliability and seamless integration, offering a perfect drop-in solution for systems handling corrosive media, high-purity liquids, and abrasive slurries. With a focus on dimensional interchangeability and backed by comprehensive technical support, we ensure minimal downtime and maximum operational efficiency for our global clientele across diverse markets from North America to Southeast Asia.

This valve is designed to be a direct, one-for-one replacement for existing valves in corrosive service, eliminating the need for costly piping modifications. Its core construction features a robust body available in various materials, lined with high-grade virgin PTFE (Teflon). This lining provides exceptional chemical resistance against a vast array of aggressive fluids, ensuring long service life and preventing product contamination.

Superior Corrosion Resistance: The PTFE lining is inert to most chemicals, acids, and solvents, protecting the valve body and providing a non-stick, non-contaminating flow path ideal for chemical processing, pharmaceutical, and food & beverage applications.
Dimensional Interchangeability: Engineered to match the face-to-face dimensions and bolt patterns of popular industry-standard valves, our product allows for quick and easy replacement without altering existing pipelines, saving significant time and installation costs.
Bubble-Tight Shut-off: The precision-machined PTFE seat and disc design ensures reliable, leak-proof sealing, even after numerous cycles, enhancing system safety and preventing product loss.
Low Maintenance & High Durability: The corrosion-resistant materials and robust design minimize wear and tear, reducing the frequency of maintenance and lowering the total cost of ownership.
Versatile Configuration Options: Available in wafer or lug styles, with various disc materials (316SS or PTFE coated) and manual or automated actuation options to suit specific process requirements.

Technical specifications for standard models are outlined below:

Parameter	Specification
Size Range	DN50 (2") to DN600 (24")
Pressure Rating	PN10 / PN16 (150 psi / 300 psi)
Temperature Range	-20°C to 200°C (-4°F to 392°F)
Body Material	Carbon Steel, Stainless Steel (304/316), Ductile Iron
Lining Material	Virgin PTFE (Polytetrafluoroethylene)
Disc Material	316 Stainless Steel, PTFE Coated Steel

Frequently Asked Questions (FAQ)

Q: What does "direct replacement" specifically mean for this valve?
A: It means our valve is manufactured to match the face-to-face dimensions, bolt hole circle diameter, and bolt hole size of common industry-standard butterfly valves. This allows you to remove the old valve and install ours using the existing bolts and gaskets without any pipe cutting or flange realignment.
Q: Is the PTFE lining suitable for all chemicals?
A: Virgin PTFE offers excellent resistance to a very wide range of chemicals, including strong acids, bases, and solvents. However, for specific media like molten alkali metals or certain fluorinated compounds, it's advisable to consult our technical team with your fluid's full chemical composition for confirmation.
Q: Can this valve be used for both on/off and throttling service?
A: While primarily designed for reliable on/off (isolation) service, the valve can be used for moderate throttling applications. For precise flow control, especially with automated actuators, we recommend discussing your specific process parameters with us to ensure optimal performance.
Q: What types of actuators are compatible?
A: The valve is designed with a standardized mounting pad compatible with most industry-standard electric and pneumatic actuators. We can supply the valve as a manual unit or provide a complete actuated assembly tailored to your control needs.
Q: How does the temperature range affect the valve's performance?
A: The standard temperature range of -20°C to 200°C covers many industrial processes. Prolonged exposure at the upper limit may affect the mechanical properties of PTFE. For applications outside this range, special design considerations are available upon request.
Q: What is included in your "technical support"?
A: Our technical support includes assistance with product selection based on your service conditions, installation guidance, troubleshooting advice, and providing material certifications and detailed dimensional drawings for engineering approval.
Q: Are special linings or disc materials available?
A: Yes. While virgin PTFE is standard, we can offer alternative fluoropolymers like PFA or modified PTFE for specific needs. Disc materials can also be customized, such as using Hastelloy for extremely corrosive environments.
Q: What is your lead time for orders?
A: Lead times vary based on size, material specification, and order quantity. Standard configurations typically have shorter lead times. We provide accurate delivery estimates upon receipt of your detailed inquiry to ensure we meet your project schedule.
