Peformance:
When the system is full of water, the air in the water continuously escapes to the highest point due to temperature and pressure changes. When the air pressure is greater than the system pressure, the buoy will fall and drive the valve stem downward, the valve port opens, and the gas is continuously discharged.
When the air pressure is lower than the system pressure, the float rises and the valve stem moves upward, and the valve port closes. The automatic exhaust valve is in such a continuous cycle operation!
The exhaust valve can also be used in conjunction with the isolation valve to facilitate the maintenance of the exhaust valve.
