Issue:
Why is the MK2-7XXX Series Actuators obsolete?

Product:
Valves and Actuators

Environment:
Maintenance

Cause:
Replacement

Resolution:
The 2 in the MK2 p/n means it has a High Temp Diaphragm, which is no longer.   The -126 means it has different fittings.   A standard temp diaphragm  MK-7121 actuator can be used with a KEL-B-571 fitting will work for a substitute noting the absence of the high temp diaphragm
