Answer / swapnil pawar
Pressure relief valve is used were air pressure is
maintained .It is pressure relief valve which maintains
pressure.
For e.g.
If in air cylinder 10kg air pressure is maintained, then if
by chance air pressure increases to 11kg the Pressure
relief valve get activates and 1kg pressure release.
This is used for safety reason.
