Combination Air Release Vacuum Breaker Valve
33a high performance combination air release vacuum breaker valve 33a series designed to protect pipelines and vertical turbine pump applications from air lock and vacuum collapse the cla val model 33a high performance combination air release vacuum breaker valve eliminates air and prevents vacuum formations in in waterworks piping systems.
Combination air release vacuum breaker valve. Air vacuum valves allow large volumes of air to be exhausted from or admitted into a pipeline as it is being filled or drained. Val matic clean water air valves are certified to nsf ansi standard 61 for drinking water components. All val matic air valve floats are unconditionally guaranteed. Apco air vacuum valves combination air valves avv design features.
While the system is flowing and under pressure air release valves continually and automatically exhaust the small quantities of air that would otherwise collect at system high points. The large air vacuum and the small air release orifices are both open during filling with the majority of the air is passes through the large orifice. Designed to protect pipelines and vertical turbine pump applications on offshore platforms from air lock and vacuum collapse the cla val model 33a high performance combination air release and vacuum breaker valve eliminates air and prevents vacuum formations in pipelines a large venting orifice and large float clearances freely exhaust or admits air during pipeline filling or draining. Operation while the air release valve is isolated and under repair.
Air vacuum valves are float operated and have a large discharge orifice equal in size to the valve s inlet. The rate at which air is discharged is a function of the differential pressure across the air vacuum valve. Air valves cla val air release valves for water systems and combination air release and vacuum breaker valves protect your piping system by automatically eliminating air pockets and preventing vacuum formations from building up in the pipeline during filling or draining operations. 33a high performance combination air release and vacuum breaker valve 33a designed to protect pipelines and vertical turbine pump applications from air lock and vacuum collapse the cla val model 33a high performance combination air release vacuum breaker valve eliminates air and prevents vacuum formations in waterworks piping systems.
Combination air valves perform the functions of an air vacuum valve exhaust large quantities of air on start up admits air on shut down and air release valves release air continuously during operation to maintain system efficiency and prevent pipeline surges. This ensures the system will remain free of trapped air and sewage gases thereby increasing system efficiency and reducing pumping cost.
