Wabco 4721754260 2/2 Solenoid Valve

Description

The 4721754260 Wabco 2/2 Solenoid Valve is a crucial component in air brake systems, responsible for controlling the flow of compressed air to actuate brakes and other pneumatic devices in commercial vehicles. This normally open valve features M10 x 1 and M12 x 1.5 port threads, a 4.0 mm nominal diameter, and operates effectively with a maximum pressure of 16.0 bar. Its robust construction, boasting IP 6K9K / IP 6K7 protection, ensures reliable performance in harsh environments. The valve utilizes a Bayonet DIN 72 585 A1-2.1-Sn/K1 electrical connection, operates at 24V with a current draw of 690 mA, and is designed for temperatures ranging from -40°C to +80°C. The valve dimensions are 63 x 123 x 39 mm, and it adheres to OE specifications for seamless integration and consistent performance.

Key Features & Benefits

Basically, this valve controls airflow in your air brake system. The “2/2” part means it has two ports and two positions – open or closed. It's electrically operated; when it gets a signal, it either lets air through or completely blocks it. Think of it like a really fast, electrically controlled gate for air. It's a simple on/off switch for pneumatic pressure. It's used in a bunch of places in the air brake system, but often you'll find it controlling things like the air suspension, trailer supply lines, or even used in emergency brake applications. It’s usually a key component in activating or deactivating a specific air function. It doesn’t handle the main brake pressure, but directs air to activate secondary systems.

Symptoms, Risks & Replacements

This valve is pretty crucial for safety and proper function. If it fails, the system it controls won't work correctly. You’ll notice if it’s going bad usually because the function it’s supposed to operate—like leveling suspension or applying a parking brake—becomes unreliable or doesn't work at all. It acts like a shield, protecting the rest of the air system from pressure issues, and if it goes, everything behind it might suffer. You can find a good selection of these at places like Fixparts Online, but make sure you get the right one for your specific setup. Replacing a faulty valve is usually a pretty straightforward job, but get a professional to look at it if you’re not comfortable working with air brake systems.
