http://en.wikipedia.org/wiki/Check_valve
from the above wiki link I have understood basic concepts on Check Valves
Suppose I Heat a gas ( air ) in a closed vessel.
It's temp and pressure increase. As soon as the pressure reaches ( or exceeds??) the cracking pressure , the valve opens and I transfer the heated gas to another vessel ( at a lower pressure and temp)
For How long will the Valve remain open
1: Till the pressure in the heated vessel drops below the Cracking pressure
or
2:Till the pressure in both the vessels is evened out ( ie the valve closes to prevent back flow)
Also are valves available that can be adjusted to work on different ( a small range of say 30-35 psi) pressures
