Air Release Vacuum Breaker Valve

Val matic clean water air valves are certified to nsf ansi standard 61 for drinking water components.

Air release vacuum breaker valve. 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. Air release valves provide high capacity venting of gas at system start up while degassing valves vent trace amounts of gas as it occurs during system operation vacuum breakers open automatically in response to minimal vacuum to prevent unwanted siphonage or collapse of storage tanks. Suitable for all high points in a water distribution transmission system. This ensures the system will remain free of trapped air and sewage gases thereby increasing system efficiency and reducing pumping cost.

Vacuum breaker air valves for critical applications where vacuum protection is a must or where column separation is predicated a vacuum breaker is used. These air release vacuum valves feature cast iron construction with 316 stainless steel float and internal components. Cla val pacific 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. Also known as large orifice air vents vacuum breakers low pressure air vents or air relief vents.

Large venting orifices and large float clearance exhaust and admit air as needed during pipeline filling and draining. Cla val air release valves for water systems and combination air release and vacuum breaker valves protect industrial and wastewater piping systems from damage by automatically eliminating air pockets admitting air when appropriate to the application and preventing vacuum formations from building up in the pipeline during filling or draining operations. From the smallest simple lever air release valve to the largest surge suppression combination air valve all are provided standard with type 316 stainless steel trim and floats. The vacuum breaker is mounted at critical pipeline high points penstocks or tanks and allows for rapid inflow of atmospheric air to reduce vacuum conditions in piping systems.

Plast o matic degassing vent vacuum breaker valves automatically seal bubble tight when not in use. The float ball type air release vaccum breaker model nk ar17 series was designed manufactured and tested for allowing atmospheric air through the valve to rapidly displace draining liquid in the pipeline and prevent internal negative pressure damaging the arrangements potentially. They help to incorporate both an air release valve and an air vacuum valve into 1 compact unit. Install before water meters or metering valves to ensure there is no air in the line for accurate flow readings.
