Description

VYR-39 TRI-FUNCTIONAL AIR RELEASE VALVES TRI-FUNCTIONAL (AUTOMATIC) Triple Effect Air Release Valve (glass fiber to extract and impel air from and into irrigation systems). FEATURES 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. It provides automatic control, eliminating any residual air pockets from reaching the valve. This causes the float to drop, partially or totally opening the discharge outlet. The system pressure does not prevent this function from being carried out. (ONLY IN TRIPLE FUNCTION VALVES) It prevents the pipes from collapsing due to pressure decrease when the system is emptied. As the system is being emptied, the float drops and opens the seal, allowing air to enter the pipe.
