Fluorine Lined Butterfly Control Valve

A fluorine lined butterfly control valve is a compact, space-saving quarter-turn modulating valve featuring a metallic disc and inner body encapsulation thick-molded with chemical-grade PFA or PTFE fluoropolymers. Engineered to provide precise throttling control in large-diameter, highly corrosive fluid lines, the fluorine lining resists almost all industrial chemicals while delivering a low-friction surface that reduces actuation torque. Conforming to standards such as API 609, EN 593, and IEC 60534, these lightweight, chemical-proof control valves are critical specifications in flue gas desulfurization (FGD), acid recovery plants, and pharmaceutical chemical headers, allowing plant automation managers to eliminate corrosive body attack by importing certified fluorine lined butterfly control valves directly from leading manufacturers in China via our advanced B2B commercial platform.
