In pipeline water hammer negative, air valve opening, so that the tube Daowai air into the pipeline, lest in the pipe produced larger negative pressure, play a protective role; operation of the pipeline system, when the pipeline internal pressure or temperature changes and dissolved in the water of the air is released, air valves will be the timely discharge, prevent pipeline information of gas and affect the operation of the pipeline system.
1. Can eliminate the gas in the pipe, reduce drag and save energy.
2. When the pipe is under pressure, the product can automatically inhale air to prevent the pipe from bursting
3. Floating ball is stainless steel, long service life, safe and reliable.
