It works on the principle that the pressure fluctuations that occur during the filling and discharging of the material in silos and hoppers do not damage the silo and silo top filter by opening the valve and venting to the outside. The silo safety valve manages the pressure balance effectively. Thanks to its automatic activation feature, it detects pressure increases in the silo and reacts quickly. This feature is essential to protect the structure of the silos and ensure occupational safety.
