Increased reliability and operational safety due to built-in thermic and overload protection of the electromotor. I have a feeling that it is the motorised bit and not the body (although can't be sure), simply because it gave trouble a couple of times during the winter (heating control said that heating was on, but valve hadn't moved and the boiler wasn't running, presumably as there was no demand for heat) but switching off at the mains and back on resolved it.
