Semi Trailer Relay Valve

ME707196 Semi Trailer Relay Valve belongs to RELAY VALVE. The relay valve is a critical component in pneumatic braking systems, designed to amplify control pressure signals for rapid braking response. When the brake pedal is pressed, it instantly converts weak control pressure from the brake valve into strong output pressure to actuate brake chambers, reducing lag time-especially vital for long-wheelbase vehicles or trailer rear axles. Its dual-chamber design balances front/rear braking force, preventing insufficient pressure due to long air-line distances, thereby enhancing braking efficiency and safety.

ME707196 Semi Trailer Relay Valve belongs to Air Brake Valve. The port thread 11 and port thread 12 are both 1/2 NPT in size. The port thread 21 and port thread 22 are both 1/2 NPT in size. The port thread 4 is 3/8 NPT in size.
