Kinetics. It will be used to evacuate large quantities of air from the pipeline, generated mainly by system causes (pump start-up, piping filling, etc.) and to introduce air from the atmosphere to the pipe (pipe emptying). The kinetic effect remains completely closed as long as there is pressure inside the pipe and does not open again until the system is drained or negative pressure appears. Its dynamic design allows the air to be purged at high speed.
Simple effect or automatic. It will be used only to evacuate small quantities of air from the pipe, produced mainly by own causes of the fluid, automatically through the small hole in the top, this hole has been designed to remove more air avoiding seals and losses.
Double effect or trifunctional. It combines the functions of the automatic effect and the kinetic effect. They have two holes for the evacuation and admission of air. During the filling of the pipes the water is pushing the air, which is being evacuated to the atmosphere through the large orifice of the valve. The small automatic effect hole remains open during this process. When the net is under pressure, the small orifice opens automatically when small pockets of air created by the turbulences of the fluid are detected.
CHARACTERISTICS AIR RELEASE VALVE NET
Suction cups specially directed to the sectors of agriculture, swimming pool, public works and industry.
Body made of PPFV and PA plastic materials.
Base made in PA with option in brass.
Maximum tightness at low pressures.
Avoid the effect of water hammer.
They prevent ruptures due to collapse caused by the vacuum in operations of emptying of fi lters, deposits and especially in
Ducts made of metal pipe.
It avoids cavitation phenomena in pumping systems.
They increase energy efficiency in pumping by avoiding the flow of air in the pipe.
They prevent reading errors in flow measurements by eliminating air from the pipeline.
The diameter of the suction cups will generally be greater the larger the diameter of the pipe in which they are to be installed,
Although it is necessary to take into account other aspects for your choice.
Angled elbowed outlets to facilitate evacuation of expelled water.
From 1/2 "to 3".
PN 16 in PPFV and PN 25 in PA.
RECOMMENDATION FOR LOCALIZATION OF AIR RELEASE VALVE
Points in which the line of current varies with respect to the piezometric line, double effect.
High points of the pipe (valve casing), double effect.
Long branches of uniform slope, double effect, one every 500m.
Output of pumping groups, kinetic effect at a high point before the check valve.
At the input of measuring instruments (counters), double effect.
At the outlet of pressure reducing valves, simple effect.
Reductions of pipe diameter, simple effect.
Filtration heads, double effect at a high point.
