Once the opening pressure given in the table is exceeded, GN 883 breather valves will vent into a container and so protect against excessive internal container pressure.
They also feature very compact dimensions.
The simple function principle (pressure spring / ball) ensures long and trouble-free use of the valve. The installation position is vertical to the top.
Temperature resistant from -22° F to 212° F (-30° C to +100° C).

See our Technical Section for pipe thread size details.
