The WABCO RELAY VLV/KIT is a vital component in a truck’s air brake system, working in conjunction with the ABS Electronic Control Unit (ECU) to modulate brake pressure and prevent wheel lockup during braking. Designed for 4S/4M systems and operating on a 12-volt electrical system, it offers precise and rapid brake actuation control. With a crack pressure typically at 5.5 psi and a maximum working pressure of 145 psi, this relay valve enhances braking safety and responsiveness.
