D37A1F-16CF Fully PTFE-Lined Butterfly Valve

TWT Fully PTFE-Lined Butterfly Valve

ال TWT Fully PTFE-Lined Butterfly Valve is engineered specifically for severe-service applications involving highly corrosive, ultrapure, or aggressive fluid handling. Featuring a complete fluoropolymer encapsulation over both the internal body and disc, this high-reliability quarter-turn valve guarantees absolute isolation between process media and external metallic components. It serves as an ideal, highly cost-effective alternative to expensive exotic alloy valves in chemical processing, pharmaceutical, and water treatment industries.

Key Engineering Features & Performance Advantages

• Full Fluoropolymer Protection: High-density PTFE/PFA lining completely encapsulates the valve bore and disc surface, providing exceptional resistance against strong acids, alkalis, salts, and aggressive organic solvents.
• Advanced Pinless Disc-to-Stem Drive: Utilizes a heavy-duty spline or square drive shaft connection without exposed pins, eliminating potential leak paths and preventing media penetration to the internal stem.
• Low Operational Torque (>40% Reduction): The inherently low friction coefficient and self-lubricating properties of PTFE reduce operating torque by more than 40% compared to standard elastomer-lined valves, allowing smaller, cost-saving actuators
