Obsolescence of Satchwell AZ2401 Rotary Actuator


The Satchwell AZ2401 actuator would normally have been installed on a Satchwell MBF Valve Body.

The Actuator comprised a 6 wire electrical connection enabling it to be operated from a Satchwell Z Monotronic or CZT Climatronic Proportional Controller as follows :- 

Terminal 1 – Open signal

Terminal 2 – Close signal

Terminal 3 – Common 

Terminal A – 135 ohm Feedback Potentiometer – winding

Terminal B – 135 ohm Feedback Potentiometer – wiper

Terminal C – 135 ohm Feedback Potentiometer – winding

If all 6 wires are connected then the AZ2401 actuator may be replaced by following SE actuators :-

MD20B-24 + Linkage Kit 914-1070-000 from Schneider Electric and an accessory kit  P140A from Belimo

If only 3 wires are connected, that is to terminals 1, 2 and 3 then the P140 accesory kit is not required.
