The peculiar design of the Atos original ex-proof valve is now also available in stainless steel execution for hazardous and corrosive environments. Stainless steel electrohydraulic valves are made with selected inoxidizable materials for external parts, to withstand extreme and corrosive environmental conditions, and for internal components, to ensure full compatibility also with water-base and special fluids. Some of the features include: poppet type leak free, or spool type on-off or proportional, direct or pilot operated explosion proof stainless steel solenoids with ATEX 94/9/CE certification, protection mode Ex II 2G, Eex d IIC T6/T4/T3; and standard manual override pin or optional manual reset.
