Wabco 9735000590 Distribution Valve

Description

The Wabco 9735000590 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 efficient and responsive braking performance in commercial vehicles. This valve features M22 x 1.5 port threads, a bolt spacing of 38 mm, and an integrated silencer (432 407 070 0) for reduced noise. Measuring 71 x 95 x 116 mm, this OE specification device ensures reliable operation and meets stringent industry standards. The quick release functionality contributes to shorter stopping distances and improved vehicle control, providing a significant safety benefit.

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.
