Wabco 4721708670 3/2 Way Solenoid Valve

Description

The Wabco 4721708670 is a 3/2 Way Solenoid Valve, a critical component within air brake systems. It is used to control the flow of compressed air, enabling and disabling functions within the braking system of commercial vehicles. This solenoid valve operates as a normally closed device, meaning it requires an electrical signal to open and allow air to pass through. It features 1/4 - 18 NPT port threads for connections and is designed for a maximum operating pressure of 13.0 bar. The valve operates on a 12V electrical system with a rated current of 1410 mA and is suitable for temperatures ranging from -40°C to +80°C. Its robust design, featuring IP 6K9K / IP 6K7 protection, ensures reliable performance in harsh environments. The valve's dimensions are 38 x 75 x 114 mm, and it utilizes air cooling to maintain optimal operating temperatures.

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.
