Combination Air Valve

On one hand it enables the full and effective discharge of air and on the other hand the air valve will close and seal tightly when water fills the valve even if the water pressure is particularly low.

Combination air valve.

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. Combination air valves are available in 2 body styles 1 single body combination or 2 custom built combination with two bodies. The two configurations perform the same functions.

60 c temporarily up to 90 c avk combination air valves are combined automatic and air and vacuum valves. And they automatically open to admit air to limit vacuum formation when the. Excessive air in a system can dramatically reduce capacity and increase. 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.

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. The sealing mechanism is built with a very soft and sensitive seal. Generally it is sound engineering practice to use combination air valves instead of simple purpose air vacuum valves. 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.

Vag ga industries figures 945 t combination air valves are triple function valves. The automatic air release function releases accumulated air from the system while it is under pressure. Combination air valve for water and neutral liquids to max. The single body is most popular due to its smaller overall size and resulting space saving inside a valve vault.

The single body combination is used where compactness is preferred. They also release air that accumulates in the valve while the system is operational.
