Queries on combination air valves
(OP)
Hi, i have a question about air valves.
Would somebody explain to me the difference between the large orifice air valve and the small orifice air valve.
I understand that the large orifice is meant to allow high volumes of air and water to enter the pipe. However, why is a smaller orifice air valve still needed and paired with a large orifice in a combination valve? Correct me if i am wrong but since the large and small orifice uses floats, when air builds up within the pipeline the large orifice also would be able to expel the air right?

The small orifice is used to release air slowly during operation while the larger orifice is used for startup and shutdown when the air volumes are much greater.
