BS EN 13397 Diaphragm Valve

A BS EN 13397 diaphragm valve is a linear-motion industrial valve manufactured, dimensionalized, and pressure-tested in strict compliance with European standard BS EN 13397. Featuring either a metallic (cast iron, ductile iron, or stainless steel) or lined body cavity, it utilizes a flexible elastomeric or fluoropolymer diaphragm compressed against a central weir to achieve positive, zero-leakage shut-off while isolating the operating stem from the media. Conforming to European Pressure Equipment Directives (PED) and standards like EN 1092-1, these highly standardized valves are primary specifications in European chemical processing facilities, water treatment plants, and industrial utility grids, allowing facility managers to guarantee code compliance and leak-tight reliability by importing certified BS EN 13397 diaphragm valves directly from leading manufacturers in China via our advanced B2B commercial platform.
