T25 2oo2 Modular Redundant Control Sytems is used for high availability & reliability applications Both solenoids are energised at the same time for increased redundancy measures. Compatiable with all hazardous area solenoids.
Datasheet
- Pneumatrol Modular Redundant Control System is operated through a NAMUR mount 3/2 or 5/2 pilot operated valve with redundant solenoid module assembly, ability to mount directly to NAMUR interface actuators
- 2oo2 Modular Redundant Control System is used for high availability & reliability applications
- Both solenoids are energised at the same time, if signal is lost to one of the two solenoids the main control valve / actuator will remain in its operating position
- Both solenoids must be de-energised in order to return the main control valve / actuator to its non-operating position
- The redundant solenoids module can be fitted to any of Pneumatrol’s standard NAMUR 3/2 or 5/2 solenoid/spring static seal spool valves which utilise the CNOMO solenoid interface
FEATURES
- External or internal pilot air connection
- Dual solenoid / spring return function
- Pilot exhaust dust cap fitted as standard
- Interchangeable CNOMO interface
- Full range of hazardous & safe area solenoids
- ATEX, IECEx, GOST CU TR and NEPSI are all available
- Body material available in aluminium (standard) & 316 stainless steel
- Low temperature & high temperature seals are available on request
- Indication ports (standard) with plugs & pressure gauges available as an option, also compatible with pressure switches
- Also known as Redundant Valve Manifold (RVM)
