ISO9001 Quality Management System
As a professional manufacturer with a strong export presence, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our specialized Marine PTFE Lined Butterfly Valve. Engineered for reliability in the most demanding corrosive environments, this valve is a cornerstone solution for industries where media compatibility and long-term performance are non-negotiable. Since our establishment in 2016, we have focused on delivering high-integrity fluid control products, backed by our ISO9001-certified quality management system. Our valve is meticulously designed to offer superior sealing and exceptional corrosion resistance, ensuring safe and efficient operation in marine applications, chemical transfer, and aggressive fluid processing systems.
Core Product Features & Technical Advantages:
- Superior Corrosion Resistance: The combination of a PTFE-lined body and 316 stainless steel disc/shaft creates a formidable barrier against a wide spectrum of corrosive media, including acids, alkalis, salts, and solvents. This dual-material protection significantly extends service life compared to standard valves.
- Excellent Sealing Performance: The resilient PTFE seat ensures a bubble-tight shut-off, minimizing leakage and preventing product loss or environmental contamination, which is critical for safety and operational economy.
- Low Maintenance & High Durability: PTFE's non-stick properties prevent scaling and buildup, while the 316 SS components resist pitting and crevice corrosion. This design reduces maintenance frequency and downtime, leading to lower total cost of ownership.
- Versatile Operation & Configuration: Available with manual lever, gearbox, or optional electric actuation for remote control. The standard wafer design is compact and lightweight, saving space and simplifying installation between flanges.

Frequently Asked Questions (FAQ):
-
Q: What media is this valve suitable for?
A: This valve is designed for highly corrosive media such as sulfuric acid, hydrochloric acid, caustic soda, salt solutions, chlorinated seawater, and various organic solvents. The PTFE lining and 316 SS offer broad chemical compatibility. -
Q: Can this valve be used for throttling flow control?
A: While primarily designed for on/off service, it can be used for moderate throttling. For precise flow control, especially with actuators, please consult our technical team for specific recommendations. -
Q: What are the available end connection types?
A: The standard design is wafer-type for installation between flanges. Lug-style valves, which allow dead-end service, are also available as an option upon request. -
Q: Is the PTFE lining prone to damage from solids in the fluid?
A: Virgin PTFE is resilient but can be abraded by hard, sharp particulates. For slurries or fluids with significant solids content, we recommend discussing your application with us for potential design considerations. -
Q: What is the lead time for orders?
A: Lead times vary based on size, configuration (actuator attachment), and order quantity. Standard sizes typically have shorter lead times. We provide accurate timelines upon receipt of your inquiry. -
Q: Do you provide custom sizes or pressure ratings outside the standard range?
A: Yes, as a manufacturer, we have the capability to engineer and produce valves in non-standard sizes or for higher pressure classes. Customization options are available and can be discussed based on your project requirements. -
Q: What kind of warranty do you offer?
A: Our products are covered by a standard warranty against material and manufacturing defects. Specific warranty terms are provided with the commercial proforma invoice. -
Q: How do I determine the correct valve size for my piping?
A: Please provide the nominal pipe size (NPS or DN), pressure rating of your flanges, and the fluid conditions (type, temperature, pressure). Our sales engineers will assist in selecting the appropriate valve model.
