Wabco 4720706280 3/2 Way Solenoid Valve

Description

The Wabco 4720706280 is a 3/2 Way Solenoid Valve, a critical component within air brake systems. It's designed for use in controlling compressed air flow, enabling functions like applying and releasing brakes in commercial vehicles and other pneumatic systems. This valve features a bayonet electrical connection (DIN 72 585 A1-3.2-Sn/K1), operates at a maximum pressure of 13.0 bar, and is normally closed. Its 4.0 mm nominal diameter and M12 x 1.5 port threads ensure compatibility with standard air brake lines. The valve's robust design, with protection class IP 6K6 / IP 6K9K and a temperature range of -40°C to +80°C, provides reliable performance in harsh environments. Measuring 38 x 62 x 112 mm, this OE specification valve offers precise control and contributes to the overall safety and efficiency of the braking system.

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.
