Information

Once the opening pressure given in the table is exceeded, breather valves GN 881 with gasket will vent into a container and so protect against excessive inside container pressure. A green colour ring marks the opening pressure of 200 mbar.
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 installation position is vertical to the top.
The valves are checked for leak tightness and opening pressure.
