Breather Valves GN 883

Type: A - Low design

Product description

Once the opening pressure specified in the table is exceeded, breather valves GN 883 will vent a container, preventing excessive internal container pressure. They are also characterized by their compact dimensions.

An identification (type A) or a colored ring (type B) in yellow (20 - 80 mbar) or green (160 - 240 mbar) indicates the different opening pressures.

The simple operating principle (thrust spring / ball) guarantees a stable and trouble-free use of the valve. The installation position is vertically upwards.

Assembly note:
For wall thicknesses below 4 mm, use thin hex nuts GN 7430.
