Pneumatic Operated Full PTFE Lined Wafer Style Butterfly Valve

Features & Chemical Resistance Excellence

• Extreme Corrosion Resistance: The valve is fully lined internally with a premium fluoropolymer, such as FEP (F46) or PFA, providing comprehensive protection against highly corrosive substances. It is suitable for use with various concentrations of strong alkalis, organic solvents, aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, and other strong acids/oxidizers in temperatures typically ranging from $-50^\circ\text{C}$ to $150^\circ\text{C}$.
• Full Lining Integrity: Features full internal lining to ensure the metal valve body and disc are completely isolated from the process fluid, offering superior resistance to chemical attack, aging, and abrasion.
• Robust Liner Adhesion: The lining utilizes a dovetail groove structure and uniformly perforated valve components to create a strong mechanical bond, preventing liner detachment and ensuring a long, reliable service life.
• Hygienic and Efficient Flow: The liner is molded for chemical stability, low shedding, and excellent anti-fouling/non-stick properties. The smooth inner wall ensures low flow resistance, a high Cv value, strong flow capacity, and reliable zero leakage shut-off.
• Compact and Lightweight: The wafer style connection contributes to its small size and light weight, making it easy to handle, operate, and install with excellent stability.
