Product Description
Material Introduction
The PTFE-lined ball valve is a high-performance industrial valve specially designed for harsh corrosive working conditions. It combines the high structural rigidity of metal valve bodies with the outstanding chemical resistance of polytetrafluoroethylene linings. Its core structure includes a durable carbon steel or stainless steel outer shell, a precision-molded PTFE inner lining and a finely polished ball core, realizing reliable pressure resistance and top-tier corrosion protection in one unit.
Adopting a 90-degree quarter-turn operation design, this valve enables fast and flexible on-off control of fluid media, with ultra-tight sealing performance to effectively prevent medium leakage during long-term continuous operation. The premium PTFE lining has excellent comprehensive performance: it is resistant to various strong acids, strong alkalis, organic solvents and corrosive media, features non-stick surface to avoid scaling and clogging, and adapts to a wide temperature range of -20℃ to 180℃, satisfying diverse industrial working temperature requirements.
It has the advantages of compact structure, easy operation and convenient installation, supporting flange, threaded and welded connection modes to match different pipeline systems. The smooth PTFE inner wall reduces fluid resistance, ensuring unimpeded medium transmission and lowering energy consumption. Its robust metal outer body resists external impact and pressure, effectively extending the valve's service life, while its wear-resistant internal components require minimal daily maintenance, reducing later operation and maintenance costs.
Widely used in chemical, petrochemical, coal chemical, pharmaceutical, metallurgical and wastewater treatment industries, this valve is the ideal choice for conveying various corrosive media. It provides stable and reliable fluid control, protects upstream and downstream pipeline equipment from corrosion damage, and meets strict industrial safety and efficiency standards. We offer multiple specifications, sizes and pressure ratings, and can provide customized solutions to meet different application needs of customers.
