Bore

AISI 5210 stainless steel.

Breather cap

Plastic, Polyamide based (PA) technopolymer. Resistant to solvents, oils, greases and other chemical agents.

Features and applications

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. <BR>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. <BR>The simple function principle (pressure spring / ball) ensures long and trouble-free use of the valve. The installation position is vertical to the top.

Material

Brass.

Sealing DIN 7603 A

Soft iron 1.0338 (for d<SUB>1</SUB>=M10x1:PA6)
