Reliable intelligent emergency shutdown (ESD) valves and actuators with Neles™ ValvGuard™ intelligent valve controllers improve your plant safety cost efficiently. In Neles we have combined our know-how of valves, actuators, safety standards (IEC61508/61511), applications, system operability and partial stroke test devices with intelligent prediction tools. Diagnostic information is presented understandably to enable planned maintenance of potentially failing valve assemblies before they have a chance to impact the process or safety.
RCI9H2 is intended to be used together with the Neles ValvGuard VG9000H. It is needed when a 24 VDC output (DO) is used in the safety system. RCI9H2 is connected between the safety system and the field device VG9000H. The primary function of RCI9H2 is to convert a safety DO into a SIL 3 compatible 4-20mA current signal. RCI9H2 also provides relay outputs for monitoring the test and alarm status of the VG9000H.
Neles NDX valve controller provides a solution for all valve brands in a wide range of applications regardless of customer or industry. The product delivers all the robustness and reliability you’d expect from a valve controller by Neles. At the same time it is extremely easy to install and use.
Neles ND9000 is designed to operate on every control valve actuator and in all industry areas. ND9000 is a smart, reliable and future-proof positioner with life-time support. Its superior design features and unique diagnostics provide a solid foundation for performance optimization and proactive maintenance.
Neles ValvGuard is a top class intelligent safety solenoid with partial stroke testing features for emergency shutdown and venting valves. Based on the automatic PST and other diagnostics data, VG9000 increases safety and plant safety targets can be reached more economically than with other solutions.
Neles SwitchGuard is a top class intelligent on/off valve controller designed to operate on any valve actuator. Large pneumatics capacity and embedded diagnostic features enable users to guarantee the availability of their switching and high cycling valves in demanding processes.
Neles NE700/NP700 positioners are designed to operate on every control valve actuator and in all industry areas. They offer a rugged construction with few parts. A small moving mass and rigid mounting provide excellent resistance to vibration. NE700/NP700 positioners provide excellent repeatability and accuracy, with either rotary or linear control valves in a wide range of applications.
The Axiom AMI platform integrates solid state valve monitoring capabilities with discrete solenoid control for process on/off automated valves. It is suitable for most hazardous locations and general purpose process applications.
