OLAER Non return valves
OLAER Non return valve type “Claboule”
These non return valves are used in sewage pipelines. They prevent the backflow of the water to the pumps, thus preventing the emptying of the pipeline.
OLAER Non return valve type “Clasar”
These non return valves with concentric rings are used in water, purified water and chemical applications. Its extremely fast obturation avoids pressure peaks as well as valve hammering.
“Perforated” Double non-return valve
Prevents an oscillatory flowing back of the water column in the system.
