Neles valve controllers cover several core product series to meet the selection requirements of different control systems. For intelligent control and precise positioning, the NDX and ND9000 series serve as intelligent valve controllers and positioners, supporting multiple fieldbus protocols and advanced diagnostics for digitally integrated, bus-driven systems. The NE700/NP700 series consists of classic pneumatic/electrical valve positioners, providing basic mechanical or electrical signal actuation and control. For on-off and safety applications, the SG9000 series is used for intelligent on-off valve control, while the VG9000 series is an intelligent safety solenoid valve supporting the high safety integrity level of SIL 3. During selection, users should match the product to the fieldbus protocol, pneumatic/electrical actuation method, and safety integrity certification level of the safety instrumented system (SIS).
