UNIRAIN ARV-1″-A
Automatic Air Release Valve
Performance
– Extracts air from small pipes as they fill. When water reaches the inside of the valve, the float rises and seals the discharge outlet.
– Maintains automatically and continuously its function of eliminating any residual air pockets reaching the valve, as the float immediately drops and the closure outlet is partly or totally opened. Water pressure does not interfere with this function.
– Prevents small pipes from collapsing. At the smallest decrease in pressure, the float drops and opens the seal allowing outside air to enter the pipe immediately.
