P13 Plastic intake and exhaust valve

Product description
The air valve adopts positive pressure exhaust and negative pressure intake design, with exhaust and intake functions. The exhaust valve automatically
discharges the small amount of air accumulated in the pipeline when the pipeline is under pressure. When the negative pressure pipe is emptied, the air is
automatically fed to keep the water flowing smoothly. Especially when the water column is separated, it will automatically open, and air into the pipeline to
eliminate the vacuum.
Working principle
▲System water injection: During the system water injection process, a large amount of air is discharged from the intake and exhaust ports. Ater the water enters
the air valve chamber, the float ball closes the inlet and outlet ports as the liquid level rises. The aerodynamic valve body design and the floating ball anti-blow-up
design can prevent the floating ball from being blown up by the high-speed airflow before the water enters the air valve and causing the exhaust port to close
prematurely.
▲System under pressure: When the system is under pressure, the intake and exhaust valves remain closed.
▲System negative pressure state: When the system is emptied, a negative pressure difference is formed, the air pushes the float downwards, and the air enters
the air valve to avoid the formation of negative pressure in the system.
