Description

The Wabco 4342050310 is a 3/2 way directional control valve designed for use in air brake systems. This valve controls the flow of compressed air to actuate components like brakes and clutches. Measuring 45 x 95 x 57 mm, this device features a 5 mm actuating range and push actuation (M6). It offers reliable performance with a maximum operating pressure of 10.0 bar and a nominal diameter of 5.0 mm, ensuring precise and efficient control within the air brake system. The valve’s exhaust is via a hole in the body and it mounts using M26 x 1.5, with port threads of M12 x 1.5. This valve is manufactured to OE specification and operates effectively within a temperature range of -45°C to +80°C.

Key Features & Benefits

This valve basically manages airflow in your air brake system. Think of it like a traffic controller for the air. “3/2 way” just tells you how it works – three ports for air to enter and exit, and two positions it can switch between. One position allows air to flow, the other blocks it. It’s pretty simple mechanically, but vital for how things operate. It’s typically used for things like controlling a single air cylinder, or activating a smaller component within the system. In your vehicle, it’s most likely controlling something like the air shift for your transmission, or maybe a lift axle if you have one. It receives a signal – usually air pressure from your brake pedal or a control switch – and that tells it to open or close, directing the airflow to whatever it's controlling. It's a key piece in getting a pneumatic system to do something.

Symptoms, Risks & Replacements

If this valve fails, the component it's controlling just won’t work. You’ll notice if it’s for your transmission shift because your gears won’t switch properly. If it’s controlling something else, like a lift axle, you’ll find that system unresponsive. It’s not usually something that will cause a total brake failure, but it will definitely impact functionality. You can find these pretty easily, even at places like Fixparts Online if you need to replace one. Getting the right one for your specific application is key, so double check your part number before you order.
