Product Description
Inversion Valve
Features & Benefits

Bendix Air Brake Inversion Valve
Spring-brake control under changing pressure conditions is the purpose of the Bendix Air Brake Inversion Valve, which manages air differently from a standard relay or quick-release valve. The Bendix 280758N opens its inlet at 30 psi and adds a dust-shielded exhaust for operation from -40°F to 200°F. The control side uses a 1/8-27 NPT port, while 1/4-18 NPT supply and delivery connections carry the main pneumatic flow. Those pressure, port, and temperature details work together as practical fitment checks for the spring-brake circuit where this valve is used.
