Issue
The MVB actuator is no longer available from Schneider Electric
Replacing a Controlli S300 Actuator
Product Line
Field Devices
Environment
- VMB valves
- MVB actuators
- S300 actuator
Cause
Only the actuator requires replacing but the MVB is no longer available from Schneider Electric.
Resolution
Note: The MVB actuators are still manufactured by Controlli, but not distributed by Schneider Electric.
- Use the AG52 valve linkage kit 880-0129-000.
- For the Controlli MVB22, MVB26 and MVB28 or S300 replace with the MV15B-230 actuator
For the Controlli MVB46 replace with the MV15B-24 actuator
For the Controlli MVB32, MVB52 and MVB56 replace with the M800 880-0310-030 actuator
If a D36 auxiliary switch was fitted in the the MVB actuator or if the auxiliary switch was used in the S300 actuator then the following auxiliary switch packs can be used:
- M800, use the 880-0104-000 kit or order the M800-S2 880-0311-030 actuator which includes 2 auxiliary switches.
- MV15B-24/230, use the 880-0469-000 kit.
Note: if the valve also requires replacing see VSB, VSB..F, VMB, VMB..F Schneider Electric replacement valves.
