The Neles ND9000 is the only intelligent valve positioner specifically engineered for hygienic and aseptic processes. Featuring electropolished 316L stainless steel housing (Ra ≤ 0.4 µm), full drainability, and 3-A, EHEDG, FDA, and USP Class VI certifications, it ensures zero contamination risk in pharmaceutical, biotech, and high-purity food & beverage applications. Retaining all ND9000 diagnostics (valve signature, performance monitoring) and ultra-low air consumption, it is the preferred choice for diaphragm, angle seat, and butterfly valves in sterile service.
