Why is the bonnet of a pressure relief valve vented?


Why is the bonnet of a pressure relief valve vented?

The Bonnet is vented to ensure that the pressure area of the bellows or piston will always be exposed to atmospheric pressure and to provide a telltale sign should the bellows or piston begin to leak. Variations in back pressure, therefore, will have no effect on set pressure.
