The AVIO® and AVIS® gates are valves that regulate a constant downstream level in basins and canals.
They regulate the water level independently of their opening, the upstream water level and the flow rate.
These valves are divided into two groups:
AVIO® valves for loaded orifices.
AVIS® valves for surface openings.
These valves can be installed :
for downstream control of irrigation networks...
for water intakes and constant flow return structures
at the head of the channel banks, for level adjustment
The main characteristics of these valves are :
the absence of any auxiliary transmission
excellent accuracy and sensitivity of the set level, depending on the adjustment and balancing of the device
bottom flow of solid deposits
fixed set level (no variations possible)
Construction :
AVIO® and AVIS® valves are made of sheet metal, tubes and steel profiles assembled by welding.
