Mid position valve?

Could someone please tell me if:

Honeywell 28mm V4073A
Siemens 28mm MVA328
Landis & Gyr MV-A328

Motorised valves are fully interchangable, is the internal wiring the same?

All are 5 wire same function but not compatible

If the wiring colours in the leads are the same AND they have the same number of leads then you will be ok.
