Replacing a Controlli MVB actuator on a VMB valve Replacing a Controlli S300 Actuator


The MVB actuator is no longer available from Schneider Electric

Replacing a Controlli S300 Actuator


VMB valves

MVB actuators

S300 actuator


Only the actuator requires replacing but the MVB is no longer available from Schneider Electric.


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 is used in the MVB actuator or if a S300 actuator was fitted then use the following:

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 Lessons Learned #13240.
