ZQF-1 type fire breathing valveDetailed product description：

ZQF-1 type fireproof breathing valve

The breathing valve is installed at the top of the storage tank to solve the problem of positive and negative pressure gas inside the tank, so that the liquid in and out of the tank is not obstructed. When the external liquid is input into the tank, a large amount of gas is exhaled (called positive pressure).

When the liquid inside the tank is exported, it must be sucked into the tank from the outside air (called negative pressure).
If the breathing valve automatically closes when the work stops, it will not leak the liquid and gas inside the tank, which ensures the quality of the liquid inside the tank.

ZQF-1 fire breathing valve is suitable for various materials such as petroleum, chemical, pharmaceutical, energy, special liquids or gases.
