Wabco 4420191651 3/2 Way Solenoid Valve 24V DC

Description

The Wabco 4420191651 is a 3/2 way solenoid valve designed for use in air brake systems. It functions as a switching element to control the flow of compressed air within the braking circuit. This valve is commonly found in commercial vehicles and other pneumatic systems requiring precise air control. The valve features a normally closed configuration, opening upon receiving a 24V DC electrical signal. Its robust construction, with dimensions of 43 x 90 x 65 mm, and IP66/IP68 protection class ensures reliable operation in harsh environments. Key specifications include a 13.0 bar maximum operating pressure, a 0.8 mm stroke, and electrical connection via Bayonet DIN 72 585 A2-2.1-Sn/K1.

Key Features & Benefits

This valve basically controls airflow in your air brake system. The “3/2 way” part just tells you how it works—it has three ports for air to move through and two positions—it either allows air to flow or blocks it. The “24V DC” simply means it needs 24 volts of direct current to operate—that’s powered by your vehicle’s electrical system. Think of it like a gatekeeper for the air. It opens and closes based on that electrical signal. This valve is used in several places within the air brake system. You’ll commonly find it controlling air to the air bags or in the trailer supply line, things like that. It's often used in applications where you need quick, controlled air movement—like releasing brakes or activating a parking brake. It acts like a switch, turning air flow on or off.

Symptoms, Risks & Replacements

It's incredibly important because the air brake system relies on precise air pressure to function correctly. If this valve fails, you’re looking at potential issues with your brakes engaging or releasing when they shouldn’t. You’ll notice if it’s going bad—maybe brakes dragging, or not holding properly. It’s a safety critical part, plain and simple. A faulty valve could really compromise your stopping power.
