Durable Valve Design with Corrosion Resistance
Built from cast iron, WCB, or stainless steel, the valve body ensures excellent mechanical strength and structural stability. Its fluorine-lined sealing surface effectively resists nitric acid and other corrosive media, maintaining consistent sealing performance and leak-free operation.
Unlike traditional valves that suffer from corrosion or leakage, the WP12-PTFE-F adopts an enhanced valve design with fluorine lining, providing a truly corrosion-resistant solution and extending the service life in harsh chemical environments.
This butterfly valve is ideal for long-term use in systems where chemical durability, tight sealing, and smooth automation are critical.
Reliable Pneumatic Actuation
The pneumatic actuation system allows smooth quarter-turn control, enabling operators to open and close the valve efficiently. Available in single-acting or double-acting configurations, this system offers fast response time and consistent torque output, ensuring both precision and safety in automated process control.

Working Principle
The pneumatic actuator of the WP12-PTFE-F utilizes compressed air to perform a quarter-turn motion, allowing the disc to open and close smoothly. When air pressure is applied, the actuator rotates the valve shaft, while return springs or reverse air pressure reset the valve position. This simple yet efficient mechanism ensures stable torque output, precise flow control, and extended service life even under corrosive medium conditions.
