Wabco 4721745040 2/2 Way Solenoid Valve

Description

The Wabco 4721745040 is a 2/2 Way Solenoid Valve, a critical component within air brake systems. This valve is designed for use in controlling the flow of compressed air within the braking circuits of commercial vehicles and heavy machinery. It functions as a normally closed valve, meaning it requires an electrical signal to open and allow air flow. The valve's dimensions are 40 x 73 x 104 mm. Its robust construction, featuring an IP 6K9K / IP 6K7 protection class and operating temperature range of -40°C to +80°C, ensures reliable performance in harsh environments. With a nominal diameter of 4.0 mm and M12 x 1.5 port threads, it provides a secure and efficient connection within the air brake system. This OE specification valve delivers precise control and contributes to the safety and efficiency of the overall braking system.

Key Features & Benefits

This valve basically controls the flow of air in your air brake system. “2/2” just means it has two ports and two positions. Think of it like a simple on/off switch for air. When the solenoid (that's the electrical part) gets a signal, it either allows air to pass through, or it blocks it. It's a pretty straightforward piece, but vital. It's used in a bunch of different places within the air brake system. You’ll commonly find it controlling air to things like the air shifter for a manual transmission, or it could be part of the system that controls the parking brake. Sometimes it’s used to activate the lift axle on trucks. Depending on where it’s located, it’s responsible for engaging or disengaging a certain function.

Symptoms, Risks & Replacements

Well, without this valve working correctly, that function it controls won’t work either. If it’s part of your parking brake system, you’ll notice if it fails – the brake might not hold. If it's controlling a shifter, you could be stuck in a gear. It acts like a shield, preventing air from getting where it shouldn't. A bad solenoid valve can cause all sorts of issues, from being unable to shift gears to a safety hazard with your brakes. You can find these pretty easily – we’ve got a good selection at Fixparts Online, and other auto parts suppliers do too. It’s usually a relatively straightforward replacement.
