Product Description


Part Number(s): 9730090020 WABCO Trailer control valve

Trailer brake valve is the role of the driver's control, cut off the trailer's air pipeline, while the air pipeline and the atmosphere connected to the brake.
Trailer brake valve has three vents: one through the air cylinder, one through the main brake valve, a through the separation switch. When the vehicle is braked, the compressed air from the main brake valve enters the trailer brake valve, closes the intake passage of the storage cylinder (wet storage cylinder), cuts off the air supply, and keeps the trailer brake valve to the separation switch air pipe Of the compressed air is quickly discharged. At this point, the distribution valve on the trailer due to gas leaving the trailer on the storage tank in the compressed air into the trailer brake chamber, together with the main car to produce braking effect. When the brake pedal is released to release the brake, the compressed air from the main brake valve is discharged into the atmosphere and the trailer releases the brake at the same time.
