Neles
Official website: www.valmet.com ↗Neles began in Finland in 1956 and grew up with the pulp and paper industry, which demanded something the globe valve of the day handled poorly: tight shut-off, high capacity and fast modulation at moderate pressure drops. The answer was rotary geometry — segment valves, ball valves and butterfly valves — and Neles became the brand that made quarter-turn control respectable in modulating duty.
Now part of Valmet, the line spans R-series segment valves for general throttling, N-series full-ball valves for tight isolation plus control, high-performance butterfly valves, and the ND9000 smart positioner with limit-switch options. Neles engineering logic differs from globe houses: less pressure recovery headroom in some designs, far more capacity per face-to-face dimension, and different noise behaviour — which is why rotary versus globe selection remains a genuine engineering decision rather than a preference.
