redundant-solenoid-system-1
redundant-solenoid-system-2
Pneumatrol has developed a valve system that is operated with two independent solenoids.
Redundant solenoid valves are used for high availability applications and functional safety.
As long as one of the two solenoids are energised the main control valve will be in its operating position, which in turn keeps the actuator/process valve in its operating position. Both coils must be de-energized in order to return the actuator/process valve to its non-operating position.
The Redundant solenoid system can be fitted to any of Pneumatrol’s standard 3/2 or 5/2 control valves which utilise the CNOMO solenoid interface.
