Product Features

The positive pressure valve chamber and negative pressure valve chamber of the 88 type all-weather breathing valve are separately separated and do not interfere with each other. It has good anti freezing performance and is suitable for use in cold regions such as Northeast and Northwest China, greatly improving the safety factor of the storage tank.

The working principle of the 88 type breathing valve is the same as that of a regular all-weather breathing valve, but due to the separation of its valve chamber and the large valve chamber, the valve disc has a sufficient jumping height, so the ventilation volume is larger than that of a regular breathing valve, and the performance is stable. This valve has the characteristics of high ventilation, low leakage, corrosion resistance, and is equipped with an electrostatic grounding wire to maintain an equipotential between the valve and the tank.
