Red Emergency Brake Valve

The 90007283 is a Kalmar Ottawa red emergency brake valve for yard trucks and terminal tractors. This air brake system safety valve controls the emergency/trailer brake circuit, providing a failsafe braking mechanism separate from the service brakes.

The red color identifies this as the emergency brake valve per DOT air brake color standards — distinct from the yellow parking brake valve (90007281). Cross-reference part numbers include 287282 and KN20025. If the emergency brake is not engaging, air is leaking from the valve, or the red knob is damaged, immediate replacement is a safety priority. Direct-fit for Ottawa T2 models.
