Combination Air Valve
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. Generally it is sound engineering practice to use combination air valves instead of simple purpose air vacuum valves. The single body combination is used where compactness is preferred. 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 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 automatic air release function releases accumulated air from the system while it is under pressure. And they automatically open to admit air to limit vacuum formation when the. 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.
Excessive air in a system can dramatically reduce capacity and increase. 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 for water and neutral liquids to max. Vag ga industries figures 945 t combination air valves are triple function valves.
They also release air that accumulates in the valve while the system is operational. 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. The air and vacuum function discharges and admits large volumes of air. 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.
The single body is most popular due to its smaller overall size and resulting space saving inside a valve vault. The d 060lp combination air valve is a low pressure air valve.
