GN 881 Breather Valves Brass


Product description


Once the opening pressure given in the table is exceeded, GN 881 breather valves with gasket will vent into a container, preventing excessive internal container pressure.

In its normal state, the gasket seals the container and prevents dirt and dust from getting inside of it.
The above diagram shows the air outlet as a factor of the opening pressure.

The valves are checked for leak tightness and opening pressure.
