Single Ball Air Valve Brief introduction:
This air release valve will effectively remove the air in pipeline and alleviate the resistance of the flow media..
Automatically suction air when the pressure is beyond limited to protect the piping system.
Features:
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 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 in formation of gas and affect the operation of the pipeline system.
Application:
In pumping station pressure tank tops and the water pipe on the installation of air valve for water conveyance pipeline during the initial water filling, regular maintenance of pipeline after water filling the air inside the pipeline to discharge, avoid pressure fluctuations.
