EN 12266 Butterfly Valve

An EN 12266 butterfly valve is a compact, space-saving quarter-turn rotary valve that has been manufactured, pressure-tested, and certified in strict compliance with the European standard EN 12266-1 (which dictates rigorous testing rates, pressure testing durations, and zero-leakage parameters for industrial valves). Featuring either a concentric or high-performance offset design, the valve's structural disc rotates 90 degrees to seal tightly against a resilient elastomer or metal seat, ensuring predictable flow isolation under high differential pressures. Conforming to European Norm guidelines including EN 593 and EN 1092-1, these highly standardized valves are essential specifications for industrial chemical processing, municipal water grids, and maritime cargo lines operating within European regulatory frameworks, allowing process plant engineers to guarantee compliance and leakage-rate integrity by importing certified EN 12266 butterfly valves directly from premier manufacturers in China via our advanced B2B commercial platform.
