Neles SwitchGuard™ SG9000 is a top class intelligent on/off valve controller designed to operate on any valve actuator. Unique embedded diagnostic features are Integrated into its design and enables users to guarantee the availability of their switching valves in demanding processes. SwitchGuard can be easily fitted to the actuator and its controlled pneumatic capacity replaces any solenoid valve providing a simple, reliable interface with the process control system. Diagnostic information is presented in easily understandable way using FDT/DTM technology, such as Neles FieldCare™, to enable planned maintenance of potentially failing valve assemblies before they have chance to impact on the process.
