Air & Vacuum Relief Valve Family:
Applications:
1.
Main Irrigation Networks - Air relief system and vacuum prevention downstream of
pumps, along supply lines and at elevations in main irrigation networks.
2.
Irrigation Control Heads - Air relief and vacuum prevention at filtration and
fertilization stations.
3.
High part of Irrigation Pipeline System - Air relief, Prevention of pipe broken
as for high pressure air.
Benefits:
1.
Pipeline Filling: During the filling process of a pipeline, high air flow is
forced out through the kinetic orifice of the air valve. Once water enters the
valve's chamber, the float buoyed upwards causes the kinetic orifice to close. The
unique aerodynamic structure of the valve body and float ensures that the float
cannot be closed before water reaches the valve.
2.
Pipeline Draining: When a pipeline is drained, a negative differential pressure
is created causing atmospheric air to push the float down.
3.
Pressurized Operation: During pressurized operation the kinetic orifice remains
closed.
