  • Product Details

  • Operating Principle:

    Under normal operating conditions, the valve disc remains closed to seal the steam. When the vacuum level inside the container increases, the disc opens to allow atmospheric air to enter. Once the vacuum returns to the normal operating pressure, the disc automatically closes and resets.

    Applications:

    • Large oil depot storage and transportation centers
    • Chemical plant liquid raw material storage areas
    • Large-scale gas storage facilities
    • Port terminal storage and transportation systems
