Cause
Obsolescence of Satchwell “M 1201” forming part of combined Actuator / 2-port Valve Body assembly.
Resolution
There is no direct replacement for the "M 1201" Actuator and as a result both the "M 1201" Actuator and the 2-port Valve Body to which it is connected will also require replacement.
Replace Satchwell “M 1201” combined Actuator & 2-port Valve Body assembly with Schneider Electric MD10B-230 Actuator, LMD-MB Linkage Kit and Satchwell MB series 3-port Valve Body of appropriate size.

N.B.
Satchwell MB series 3-port Rotary Shoe Valve Body may be converted for use as a 2-port Zone Valve by means of the installation of a plumber’s plug in Port 3
- Install plumber's plug in Port 3 of MB series 3-port Rotary Shoe Valve Body.
- Tighten plumber's plug sufficiently to ensure PN 10 rating of Valve Body is not compromised.
It is possible that the "M 1201" Actuator may have been fitted with an Auxiliary Switch.
If so then an MD-S1 Auxiliary Switch may be fitted to the MD10B-230 Actuator if required.
