Description

The Wabco 9630010530 Trailer Release Valve is a critical component within the air brake system of a trailer, responsible for applying and releasing the trailer brakes in coordination with the tractor unit.

The valve boasts a maximum operating pressure of 8.5 bar, is mounted via a 2x Ø 8.5 mm flange, and has port threads of M16 x 1.5 and Ø 21.5 mm. It also incorporates a non-return valve and a flap exhaust. The valve measures 88 x 93 x 179 mm and operates effectively within a temperature range of -40°C to +80°C, offering reliable performance and adherence to OE specifications.

Key Features & Benefits

This valve basically controls the air pressure going to the trailer's brakes. It allows you to apply and release the trailer brakes independently from your truck’s brakes – things like emergency braking, parking, and even just fine – tuning how much the trailer slows down. It manages the airflow, determining how quickly and firmly the trailer brakes engage. It also has a manual lever that lets you fully release the trailer brakes even if you have a problem with the air system – a good safety feature. Think of it as the central control point for your trailer’s braking. It sits in the air line running from your truck to the trailer, and it's how you tell those trailer brakes what to do. It’s connected to the emergency spring brakes on the trailer too, so if you lose air pressure, those spring brakes automatically kick in. It's a crucial link in making sure your truck and trailer work together safely.

Symptoms, Risks & Replacements

Well, it’s really about safety, plain and simple. Without a working release valve, you lose precise control over your trailer’s braking. You’ll notice if it’s failing because the trailer might not stop at the same rate as your truck, or it could even stay locked up. It prevents dangerous situations like trailer sway or runaways. A faulty valve can lead to a lot of trouble, so it's something you definitely want to keep in good working order. You can find these online at places like Fixparts Online, and they're usually pretty straightforward to replace if you’re comfortable working with air brake lines.
