China Linear Rotary Actuators Control Valves Neles ND7000 ND9000 Digital Valve Controller with HART Protocol SIL 2 IP66

The Neles ND7000 is an intelligent digital valve controller designed for pneumatic linear and rotary actuators in process industries. Featuring HART 7 or FOUNDATION Fieldbus communication, it offers ±0.5% positioning accuracy with advanced online diagnostics via Neles Valve Manager software. The non-contact magnetic position sensor ensures wear-free operation, while low steady-state air consumption (less than 0.3 Nm³/h) reduces operating costs. With IP66/IP67 enclosure and SIL 2 certification, the ND7000 delivers reliable performance in harsh environments, enabling predictive maintenance and seamless integration into DCS systems for oil & gas, refining, and pulp & paper applications.
