Wabco 4735010050 Distribution Valve

Description

The Wabco 4735010050 Quick Release Valve, also known as a Distribution Valve, is a critical component in air brake systems. It's designed to quickly release air pressure from the brake chambers, enabling faster response times and improved braking performance in commercial vehicles. This valve features a calculated volume of 0.6072 and a nominal diameter of 14.0 mm, with port threads of M22 x 1.5. Its dimensions are 69 x 80 x 110 mm. This OE specification valve is designed for reliability and efficiency, ensuring consistent and safe operation of the air brake system. It includes a silencer (432 407 060 0) for reduced noise and features a mounting configuration of 2x Ø 9.5 mm with a bolt spacing of 38 mm. It operates with a maximum pressure of 10.0 bar.

Key Features & Benefits

This valve basically takes the air pressure from your compressor and carefully sends it to the different air brake chambers on your truck or trailer. It manages the airflow to the front and rear brakes, controlling how much pressure goes where. It also has a safety feature – it can isolate the front and rear systems if one develops a leak, so you don’t lose all your braking ability. Think of it like a traffic controller for the air going to your brakes. It's a critical component in your air brake system, falling between the compressor and the brake chambers themselves. The compressor makes the air, this valve decides where it goes, and then the brake chambers actually do the stopping. It works with other parts like the relay valves, but this is one of the central pieces. It's typically found somewhere along the air lines, usually near the chassis, but location can vary.

Symptoms, Risks & Replacements

This valve is super important for safe stopping. If it fails, you could have uneven braking, where one set of brakes is applying much harder than the other, or you might lose brakes altogether. You’ll notice if it’s going bad—you might get a low air pressure warning light, feel pulling to one side when braking, or experience longer stopping distances. It’s a key safety component. You can find replacements for these, along with a lot of other air brake parts, over at Fixparts Online if you need one. It's definitely something you want to keep in good working order.
