Application timing can change when a relay valve uses the wrong crack setting, so the Bendix Air Brake Relay Valve should be matched by pressure behavior as well as by port layout. For the plumbing interface, the Bendix 803117 uses 1/2-14 NPT main ports with a 1/4-18 NPT control connection. This version begins delivery at 4.0 psi and sends air from one supply position to eight delivery connections. Reading those details as one system helps brake buyers confirm that both response setting and threaded connections agree with the existing multi-delivery circuit.
