FY-1 vacuum breaker valve

Description of FY-1 vacuum breaker valve

The English name is Vacuum breaker valve or anti-negative pressure valve is a valve that helps balance vacuum pressure in pipes, tanks, filter tanks, and closed water supply systems.

When the water pressure in the closed system is positive, the negative pressure valve will close, forming a closed system with complete positive pressure, but when the system is stopped or the water demand is higher than the pump supply system, the phenomenon will occur. Negative pressure will take place inside. Then the anti-negative pressure valve will open to let air flow in to balance the vacuum pressure in the system. This helps to balance the pressure in the pipeline system, tanks, filter tanks and the closed water supply system is safely protected.
