Single Orifice Air Valve is an air valve with only one port for inlet and air valve port. There are two kinds of big mouth and small mouth. The large port air valve is suitable for exhausting and sucking the air. When there is no pressure water in the main pipeline, the floating ball is located at the bottom of the valve, and the orifice is open. During the filling process of the Single Orifice Air Valve, the air is discharged and the rising water level supports the floating ball to the valve seat hole, and then the water pressure in the pipe seals the valve outlet; when the drainage pressure in the pipe drops to close to atmospheric pressure, the floating ball falls. Air is introduced from the outside to prevent vacuum in the tube. For small port air valves, the floating ball is usually close to the sealing surface of the valve seat orifice. When the air accumulation in the valve cavity drops, until the floating ball loses buoyancy and automatically leaves the valve seat sealing surface, the valve opens, and the air in the valve opens from the small port. After discharge, the water level rises, floats the float and reseals. The small port air valve can remove the air continuously escaping from the water body on the pipeline.

Many people are full of praise for the advantages of Single Orifice Air Valve. So what are the advantages of Single Orifice Air Valve? Let's learn about it together.
1. The Single Orifice Air Valve float is made of low-density polypropylene material, which will not deform even if it is immersed in high-temperature water for a long time. There is no difficulty in moving the buoy.
2. The buoy lever is made of hard plastic, and the connection between the lever and the buoy and the support adopts a movable connection, which will not corrode during long-term operation, causing the system to fail to work and water leakage.
3. The sealing end face of the lever is supported by a spring, which expands and contracts with the movement of the lever to ensure the sealing performance without exhaust.
The above are the advantages of Single Orifice Air Valve.
