OLAER Bleeder and degassing valves for drinking and waste water

OLAER Bleeder and degassing valves for drinking and waste water have to satisfy various requirements. Primarily they are used for degassing while filling or emptying pipes. Degassing should also be possible under pressure. Most valves combine these functions.

The use of these valves must be carefully planned – especially with suddenly varying flow rates for instance at emergency shut downs of pumps. Pipes will have to support the vacuum an tend to collapse.

All valves can be fitted with softly closing devices, ventilation or  air-intake lock in case of flooding. Special attention should be also given to maintenance and accessibility.
