Combination Air Valve

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.

Combination air valve.

A combination air valve can be furnished either as a single body design where a singlebody contains both air release and air vacuum components or as a dual body design figure 6 where an air release valve is piped to the side of an air vacuum valve. And they automatically open to admit air to limit vacuum formation when the. The automatic air release function releases accumulated air from the system while it is under pressure. The air and vacuum function discharges and admits large volumes of air.

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. The two configurations perform the same functions. They vent air from pipelines and systems as they are being filled with water and then close tight once the system is full and pressurized. Generally it is sound engineering practice to use combination air valves instead of simple purpose air vacuum valves.

The combination air valve is available in a single body double orifice shown on page 2 or in a duplex body arrangement see page 6. Combination air valve for water and neutral liquids to max. The sealing mechanism is built with a very soft and sensitive seal. The d 060lp combination air valve is a low pressure air valve.

Combination air valves are available in 2 body styles 1 single body combination or 2 custom built combination with two bodies. The single body is most popular due to its smaller overall size and resulting space saving inside a valve vault. 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. Excessive air in a system can dramatically reduce capacity and increase.

60 c temporarily up to 90 c avk combination air valves are combined automatic and air and vacuum valves. Vag ga industries figures 945 t combination air valves are triple function valves.
