A: The length of time in question is not dependent on the vent. It is dependent on the system. Thus it will be different in every system and in every radiator; depending on pipe length and diameter. Allow me to explain. When the water in the boiler reaches 212 F the water flashes to steam. Stream is extremely powerful and leaves the boiler at roughly 55 miles per hour. The steam needs to push and clear all the the air in front of it out of the way. This is the hissing noise you hear. The hiss is made by a combination of the air and the steam that has condensed back into water, as it was cooled by the pipes, being forced out of the system by the steam. Eventually when all the pipes have been heated and all the air pushed out of the way, steam will reach the radiator. This can take some time, even though the steam leaves the boiler fast. This is because the cold pipes pulling energy out of the steam will slow it down and cause it to condense. When the steam does reach the radiator the vent locks up or closes. Since no more air can now escape, no more steam goes to that radiator. Instead the steam pressure will pick the path of least résistance to the next radiator that is not yet satisfied. When all the vents are closed, pressure in the system will build and the boiler will shut off. That is assuming the thermostat has not already been satisfied and shut the system off. When all the heat is given up by the radiators and the all the steam has condensed back into water, the vents open. This releases the vacuum and allows the water to flow back from the radiators to the boiler. Then the entire process can happen over again.

Terrible Product, Don't Buy It
I've used three of these now and they simply do not seal the steam. The effectively evacuate air in the line, but as soon as the steam hits, the valve does not close

not sure if the valve is supposed to make as...
not sure if the valve is supposed to make as much noise (rattle) as it does...and seems to "spit" as opposed to "steam" out of its opening...but the radiator certainly heats up.

You'll definitely be returning it tomorrow
It's been 1 year since I bought one of these hoping something improved.These things are not even serviceable as a paper weights 'cause they roll when placed on their side.
Home Depot should be ashamed of themselves for selling a product of this quality..... it really demonstrates disrespect for it's customers.
