The valve combines the air intake and exhaust features in one. The stainless steel body can withstand water pressure up to 20kg/cm². 

Application: High vacuum tends to result in a damaged pipeline and contaminated water entering the pipeline or damaged water meter. With the vacuum breaker valve, the vacuum caused by water column separation as well as the water hammer phenomenon can be prevented.
