Neles™ – ValvGuard VG9000 Intelligent Safety Solenoid

Neles™ – ValvGuard VG9000 Intelligent Safety Solenoid

Safe, reliable operation with diagnostics and predictive maintenance


Neles ValvGuard’s unique construction enables the diagnostics part of the device to be alive all the time and not depending on the safety part. This is a true user benefit and gives maximum availability of the diagnostics information. VG9000 is thus capable to record emergency trips with graph and key figures related to it. Large pneumatics capacity and embedded diagnostic features enable users to guarantee the reliability and availability of their ESD or ESV valves. Diagnostic information is presented in easily understandable way to enable planned maintenance of potentially failing valve assemblies before they have chance to impact on the process or safety.

We have further enhanced our ValvGuard offering with an intelligent PST solution called VG9PST. This latest development provides excellent protection against spurious trips when a customer uses an external solenoid valve, reducing the risk of consequent unwanted and costly plant shutdown.
