Double orifce air release valve
The low pressure exhaust process is divided into two stages: when the pressure difference is low, it can be used to limit the exhaust velocity. To eliminate the impact of pressure fluctuation on the system due to the full speed exhaust under special conditions such as water hammer.
When possible. It is suitable for pipeline water column separation conditions, large diameter and long distance pipeline, the main pipeline rapid water filling, deep well pump, pipeline protection system to avoid water hammer effect.
