B. Operation

The S-015 Automatic Air Release Valve releases entrapped air from
peaks and along pressurized systems where the valve should be installed.
Pockets of accumulated air may cause the f ollowing destructive phenomena:
* Impediment of effective flow and hydraulic conductivity of the system, along with a throttling

effect
as would a partially closed valve. In extreme cases this will cause complete flow stoppage.
* Accelerate cavitation damages.
* High pressure surges.
* Accelerate corrosion of metal parts.
* Danger of a high-energy burst of compressed air.
* Inaccuracies in flow metering.
