DN100 composite air evacuation vent valves PN10/16 Ductile iron

combination air valve belongs to quick exhaust valve or exhaust valve.

The exhaust valve body is a cylinder shape, composed of stainless steel float ball, lever and disc. This valve are often fixed in the highest point or closing space of the pipeline, to release air to keep the channel open and increase the efficient use of pipes and pump.



Working Principle of CARX Combination air quick exhaust valve

When injecting water into pipeline, the disc keep open to exhaust air; After the valve is full of water, then no air in it, the float ball will rise, which will drive the disc close. When the pipeline transit the water, the water level will fall if the little air gather into a certain amount, then the air will be exhausted through ostiole. But the plug will be opened quickly to absorb air when no water or negative pressure in the pipes after closing the pump, to keep the pipeline safe.
