Our fluorine-lined butterfly valves are specifically designed for high-purity and non-contaminating processes, delivering exceptional corrosion resistance, wear resistance, and leak-tight performance. Available in manual, pneumatic, electric, hydraulic, and electro-hydraulic actuation options, these valves seamlessly integrate into automated industrial systems. With nominal diameters ranging from 2" to 48" (DN50 to DN1200) and pressure ratings up to PN25/CL300, they provide versatile solutions for diverse industrial fluid handling needs.
Our zero internal leakage butterfly valves feature an innovative O-type elastic diaphragm seat with a flexible lip design. This advanced sealing mechanism ensures complete shut-off without internal leakage and provides automatic compensation for wear, extending service life and reducing maintenance costs.
The valve body incorporates a two-piece butterfly plate structure with an eccentric shaft and segmented design. The replaceable and adjustable valve seat simplifies maintenance and servicing, minimizing downtime in critical operations.
Equipped with an ISO standard mounting pad, these valves can be easily fitted with pneumatic, electric, hydraulic, or electro-hydraulic actuators. This flexibility allows for seamless integration into existing automated control systems, enabling remote operation and precise flow regulation.
Constructed from high-quality materials including ductile iron, carbon steel, and stainless steel (304, 316), our valves offer excellent mechanical strength and corrosion resistance. The fluorine lining and various seal materials provide compatibility with a wide range of aggressive media.
