GN881 Breather or Exhaust Valve
Once the opening pressure given in the table is exceeded, these breather valves with gasket will vent into a container and so protect against excessive inside container pressure.
In its normal state, the gasket closes the container and so prevents dirt or dust getting inside the container.
The above diagram shows the air outlet as a factor of the opening pressure.
The valves are checked for leak tightness and opening pressure.
