Neles™ ceramic ball valve, series E

Neles™ Ceramic Ball Valve, Series E, is a fully ceramic flow path control valve designed for highly erosive applications. The Series E ball control valves are engineered to handle the most severe erosive service conditions across a wide range of industrial sectors, including pulp and paper, petrochemical, refining, and related industries. Featuring new-generation ceramic materials for the lined flow path and trim parts, these valves are ideal for highly abrasive rotary control applications. Ceramic valves help extend plant process availability and reduce maintenance costs.

Benfites
