The QB1 single port exhaust valve is a barrel type valve body, and its internal structure mainly consists of stainless steel floating balls. This valve is divided into two kinds of exhaust valves: thread type and flange type.

Type QB1 is applicable to the pipeline with working temperature less than 80 degrees, which is used as a device to exclude gas in the pipeline.

Working principle of single port exhaust valve

When the water begins to be injected into the pipe, the floating ball will float up slowly. At this time, the valve has been discharged. When a certain pressure is reached, the float holds the rubber ring tightly, indicating that the air has been exhausted from the exhaust nozzle.
