Wabco 9735000450 Quick Release Valve

Description

The Wabco 9735000450 Quick Release Valve is a critical component within air brake systems, designed to rapidly exhaust air from brake chambers during application and release, ensuring responsive and safe braking performance in commercial vehicles. This device is used extensively in trucks, buses, and trailers. The quick release function minimizes drag and extends service life by preventing the brakes from staying partially engaged. It features dimensions of 73 x 85 x 110 mm, a nominal diameter of 14.0 mm, and port threads of M22 x 1.5. It includes a silencer (432 407 060 0) for exhaust and mounts using 2x Ø 9.5 mm bolts.

Key Features & Benefits

Basically, this valve rapidly dumps air pressure from the brake chambers when you hit the brakes, and then again when you release them. It’s a fast acting switch, you could think of it like that. It allows air to escape quickly, letting the brakes disengage faster than they would on their own. It also helps prevent the brakes from staying partially applied, which is important. It’s a small part, but does a lot. This valve sits within your air brake system, usually close to the air compressor and service reservoir. It's tied into the brake lines and controls how quickly air pressure builds and releases to the brake chambers at each wheel. It's a key component in the overall system, helping to ensure efficient and responsive braking.

Symptoms, Risks & Replacements

If this valve fails, you’ll notice if it’s dragging—meaning your brakes might stay slightly on, causing overheating and wear on your brake components. Or, it could cause slow brake response—you press the pedal, and things don’t happen as quickly as they should. It really contributes to safety and keeping your stopping power reliable. A failing valve can be a serious issue, so it’s good you’re checking it out. You can find replacements at places like Fixparts Online if you need one, and it’s a fairly straightforward swap for a mechanic.
