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.

Operating principle of FY-1 anti-negative pressure valve product
The vacuum pressure relief valve operates similar to a one-way valve, allowing air to flow from the outside into the gas, water system with negative pressure appearing from the inside, but not allowing air or liquid to flow in the opposite direction from the inside out.
Application of FY-1 vacuum breaker valve:
The negative pressure anti-valve should be installed at the highest point of the system, in some cases it can be installed below where there is the highest risk of negative pressure occurring.
Used to protect plants and equipment that cannot withstand vacuum pressure such as: heaters, saturated steam pipes, air pipes, cooking pots, presses, condensate tanks, misting systems, any equipment which way we don’t want vacuum pressure to exist.
