Wabco 9735000030 Quick Release Valve

Description

The Wabco 9735000030 Quick Release Valve is a critical component within air brake systems, designed to rapidly exhaust air from the brake chambers, allowing for quick and efficient brake release. This valve is commonly used in commercial vehicles and heavy-duty applications to enhance braking responsiveness and safety. Measuring 60 x 80 x 86 mm, this device features a calculated volume of 0.413, a bolt distance of 38 mm, and connections including G 3/8 J exhaust, G 3/8 J port thread 1, and 2x G 3/8 J port thread 2. The quick release valve operates with a maximum operating pressure of 10.0 bar and mounts using 2x Ø 9.5 mm fixings, while its 14.0 mm nominal diameter contributes to precise air flow control. This valve is manufactured to OE specification, ensuring reliable performance and compatibility.

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.
