WANVALVE WP11-F-PTFE Pneumatic Fluorine Lining Ball Valve – Complete Product Description

The Pneumatic fluorine lining ball valve WANVALVE WP11-F-PTFE is engineered for demanding industrial applications. Featuring a fluorine lined valve, it provides superior corrosion resistance, making it ideal for handling acids and alkalis as well as other corrosive media. Constructed with duplex stainless steel, it delivers excellent mechanical properties and long service life, ensuring reliable operation under high temperatures and high pressures. Its smooth surface finish also facilitates easy cleaning and maintenance.

Technology Highlights

• Fluorine Lining Technology: The PTFE fluorine lining forms a chemically inert barrier between the stainless steel body and the fluid. It resists strong acids, alkalis, and other corrosive media, reduces friction for smooth operation, and ensures long-term durability even under high temperatures. This lining also provides excellent resistance to oxidation and chemical degradation, making it suitable for a wide range of industrial chemicals beyond just acids and alkalis.

• Pneumatic Actuation Technology: Designed for pneumatic actuation using compressed air, the valve provides precise, repeatable control. Configurations include single acting (spring return) and double acting (air-to-open/air-to-close), allowing integration into automated industrial systems.

• Stainless Steel Selection: The duplex stainless steel body ensures high mechanical strength and resistance to corrosion, outperforming ordinary ball valves in demanding applications. Suitable for environments requiring martensitic or ferritic stainless steels, depending on the media and temperature conditions.

Key Features

• Anti-Corrosive Design: Fluorine lining protects against strong acids, alkalis, and other corrosive media.

• Reliable Pneumatic Operation: Precise flow control using compressed air.

• Easy Maintenance: Smooth surface finish minimizes residue buildup.

• Versatile Applications: Chemical, pharmaceutical, water treatment, and food production systems.
