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.

1)

Use the AG52 valve linkage kit 880-0129-000.

2)

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

3)

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.
