AIR VALVE DOUBLE ACTION

Description Double or triple action kinetic air valves to extract and impel air from and into irrigation systems. Made of nylon 6.6 and reinforced with 30% fibreglass. Rubber closure gasket and polystyrene float. Operating range of 0.2 to 15 bar. Continuous operation. Automatic effect. Extracts more than 500 m3/h of air on filling the installation, without the valve closing through absence of air. Extraction of more than 45 m3/h of air in installations with hydraulic pressures of 4 bar. It extracts the air from the installation while the pipelines are filling. When the water reaches the inside of the valve, the float rises and closes the discharge outlet.
