Double effect air valve RM 1'' red plastic base UNIRAIN ARV-1”A PN16.
Application:
Designed to effectively expel accumulated air in pipes, filters, tanks and any place where the presence of air is detrimental to proper operation.
The air valves are located at the exit of pipes whose slope varies in relation to the hydraulic gradient, at points where the pipe rises above ground level, in large branches with a uniform slope, at the entrance to measuring instruments, at the outlet of the reducing valves, in diameter reductions, pumps, filter systems and on each side of the crossings under roads.
For the correct operation of the valve, it must always be placed in a vertical position.
It is recommended to install a manual isolation valve under the pad to allow maintenance and repair operations without having to shut down the entire system.
Advantages:
-It has a single closure that expels kinetic air and residual air, all automatically and without the water pressure being able to impede these functions.
-Simple design, with only five pieces, its disassembly is simplified in case of having to carry out maintenance or cleaning work.
-The exclusive Y-shaped orifice design achieves a much higher air flow than other valves of this type, both in the discharge and intake phases.
-Its perfect fit makes it hermetic at very low pressures.
-Body in red for easy viewing.
Technical specifications:
-Continuous and automatic operation.
-It will evacuate at least 70 m³ / h of air without causing the valve to close in the absence of water.
-Volume of extracted air of at least 15 m3 / h at 10 mwc
-Operating pressure up to 16 Kg / cm2.
-Body and base made of polyamide reinforced with fiberglass.
-Protective treatment against ultraviolet rays.
-Male thread 1 ”.
Features:
-Extraction of air in small pipes while filling. When the water reaches the inside of the valve, the float rises and closes the outlet hole.
-It automatically and continuously maintains its purging function on any air bag that could reach the valve, since these cause the immediate descent of the float and the partial or total opening of the closing orifice. The water pressure does not prevent this function.
-Protects from crushing in small pipes, because with the minimum depression, it lowers the float, opening the closure, so that the outside air enters the pipe immediately.
