Venting valve, high version

Once the opening pressure given in the table is exceeded, breather valves GN 883 will vent into a container and so protect against excessive inside container pressure. They also feature highly compact dimensions. A coding (Type A) or a colour ring (Type B) in yellow (20 - 80 mbar) or green (160 - 240 mbar) indicates the different opening pressure ratings. The simple function principle (pressure spring / ball) ensures long and trouble-free use of the valve. The installation position is vertical to the top. Assembly instruction: For mounting on walls of less than 4 mm thickness please use a mounting nuts GN 7430.
