Wabco 4721730010 3/2 Way Solenoid Valve

Description

The Wabco 4721730010 is a 3/2 Way Solenoid Valve designed for use in air brake systems. This valve controls the flow of compressed air within the braking circuit, enabling or disabling the air supply to activate brakes or other pneumatic components. It's commonly found in commercial vehicles and industrial applications requiring reliable air control. This valve features a normally open configuration, a 4.0 mm nominal diameter, and is built to OE specification for optimal performance and durability. The dimensions of the valve are 40 x 141 x 80 mm, and it is rated for a maximum operating pressure of 13.0 bar, operating within a temperature range of -40°C to +80°C. Its robust design with protection class IP 6K6K / IP 6K9K ensures long-lasting reliability in harsh environments.

Key Features & Benefits

Basically, this valve controls airflow in your air brake system. The “3/2 way” part just tells you how it controls it. It has three ports – one for pressure in, one for pressure out, and one that vents to the atmosphere. It switches between two positions – either allowing air to flow between the inlet and outlet, or blocking the flow and venting the pressure. It’s electrically operated, so when it gets a signal from the system, it either opens or closes that airflow. You’ll find these used in a lot of different parts of an air brake system. Things like controlling the operation of air brakes themselves, the parking brake, even the air suspension on some vehicles. It’s a pretty common component for directing air where it needs to go to activate those systems. Think of it like a gatekeeper for the air.

Symptoms, Risks & Replacements

Well, if this valve fails, whatever system it controls won't work right. You'll notice if it's related to your brakes – you might have trouble applying the parking brake, or even have issues with your service brakes holding properly. It’s a safety – critical part, because it directly impacts how well your vehicle can stop. It acts like a shield, preventing air from going where it shouldn't, and letting it through when it needs to. We carry a good selection of these, and you can often find a great price on a replacement at Fixparts Online if you’re looking. It's definitely something you want to keep in good working order.
