(888) 312-8812 Login SignupRelay Valve
The Bendix Air Brake Relay Valve in this configuration begins relaying pressure at 5.5 psi, a threshold set apart from other nearby relay-valve options. The body uses two supply and four delivery connections, with the delivery side split between two horizontal and two vertical ports. The relay valve therefore combines a defined pressure threshold with a 2 SUP / 4 DEL layout. Those features give brake-system buyers practical checks for matching the Bendix 800483 to the existing pneumatic arrangement.
