1. Air release valves, also called small office valves, are designed to automatically release small pockets of accumulated air from a pipeline while the system operates under pressure exceeding atmospheric pressure.
2. Air/vacuum valves, also called large orifice valves, are designed to exhaust large amount of air automatically during pipeline filling and to inflow large amount of air automatically when the internal pressure in the pipeline drops below atmospheric pressure.
3. Combination air valves are designed to perform the same function as air/vacuum valves but, in addition, they will automatically release small pockets of air from the pipeline while under pressure like an air release valve.

There are two critical parts in the operation of a pipeline. During filling, air that occupies the empty pipe must be evacuated ahead of the incoming liquid in a controlled and efficient manner so that the surge and water hammer are minimized and liquid completely fills the pipe. During draining, whether planned or unexpected, air must be admitted into the system to replace the outflowing liquid to avoid over-vacuum and possible pipeline damage.
The air release valve is designed to release accumulated air pockets from the system, which, in the process, pressures pipelines. Air pockets increase energy consumption because pumping operations will be intensified at water heads to overcome pressured air.
Air release valves have a function related to protection from high shocks, surge pressure, water hammer, and liquid overflow from fresh or seawater pipelines.
PROSAVE's valve can provide low-cost insurance to prevent expensive maintenance costs for pipelines and pump systems.
