First, a 2 watt solenoid runs hot, but not as hot as a 4 watt, the 2 watt power consumption becomes heat eventually.

I am going to test the solenoid, to see the actual current that flow through the burkert 2822.
at this point I believe even it is a 2 watt(24V DC, 83mA), there is no circuit inside(the solenoid or the power supply) to limit the current, so when you use a 800mA max output power supply, means more current pass through the solenoid and create heat.
