They look exactly alike but they are called different names. Is there a reason this is done?

Oh Ok. Well I guess I'd just go with the garden valve then as maybe the washing machine might need a valveGarden valve would have some other features that a boiler drain would lack, including a vacuum breaker.
I don't know the term garden valve. Lawn hydrant would include freeze resistant drain feature.
A boiler drain is a valve that typically or historically would have been installed to drain a large volume of water quickly. They can open up so much in fact that you will notice a signifigant drop in water pressure in some homes. While i've never heard the term "garden valve" I would guess that is as others have guessed, a hose spigot for using to water lawns, wash cars etc.. those would typically be installed with a vacuum breaker to prevent any contaminants from being siphoned back into the drinking water. A yard hydrant is a valve that is typically free standing in a yard, has a vacuum breaker and has its frost free shut off and drain down below the frost line underground. We typically install these attached to a post and with a double check valve assembly since the drain that is connected to the valve is under ground and can become contaminated as well.
The washer doesn't need a vacuum breaker on it. A garden faucet would need the breaker to prevent siphon water from irrigation and hoses used for watering.
A boiler drain doesn't have a vacuum breaker and tend to output at a right angle while many faucets for garden hoses will have an angle away from the home. Any set rules on the angle thing though? Not sure.
This is awkward, but...
