    Product Description

    Bendix 281459N TR-3 Air Brake Inversion Valve – 25/40 PSI

    The Bendix 281459N TR-3 Air Brake Inversion Valve is a heavy-duty pneumatic control component designed to regulate compressed air flow in commercial vehicle braking systems. Commonly used in emergency and parking brake circuits, this valve responds to changes in control pressure to provide dependable air system operation.

    The TR-3 inversion valve operates by reversing its pneumatic output in response to changes in control pressure. In systems using common supply and control pressure, the valve begins delivering air when pressure decreases to approximately 25 PSI and begins exhausting when pressure increases to approximately 40 PSI.

    Manufactured with a durable metal body, the Bendix 281459N is engineered for reliable operation in demanding commercial truck environments. Its compact design, threaded pneumatic connections and straightforward mounting configuration make it suitable for replacing compatible inversion valves in heavy-duty air brake systems.
