Product Description

The principle of the exhaust valve: when there is gas overflow in the system, the gas will climb up the pipeline and finally gather at the highest point of the system. The exhaust valve is generally installed at the highest point of the system. When the gas enters the exhaust valve cavity gathered on the upper part of the exhaust valve, as the gas in the valve increases, the pressure rises. When the gas pressure is greater than the system pressure, the gas will drop the water level in the cavity, and the float will drop with the water level, opening the exhaust port.
