Boss Therm Actuator Replacement?

[TractorT20]

The Boss Therm actuator on my 3 port motorised valve has failed!
I tried getting a replacement but cannot source one.
Any ideas please where I might be able to get a replacement or a substitute ?
Or will I need to replace the whole assembly?
Thanks

Some of there control stuff was re badged Siemens may be worth a look.
Otherwise replace the lot we use E P H better price than honeywell and 4 years longer warranty.
When we swap out a 3 port prefer to swap to S plan
