The Wabco PRO0110040 Relay Valve is a crucial component within air brake systems, designed to regulate air pressure and ensure efficient braking performance in commercial vehicles. It's commonly used in trucks, buses, and trailers to control the flow of compressed air to the brake actuators. This pressure reduction valve maintains a consistent and reliable braking force, enhancing safety and control. It features M22 x 1.5 and M16 x 1.5 port threads, and is sized 150 x 125 x 125 mm. With a maximum operating pressure of 10.0 bar and a robust design, this relay valve delivers consistent performance and durability. Basically, a relay valve takes the signal from your brake pedal – that initial push – and boosts it, sending a stronger, faster signal down the air brake lines to the brake chambers at each wheel. It’s like an amplifier for your braking. It manages the air pressure, allowing a quick build – up when you apply the brakes, and then releases it when you let off. It also has a “quick release” feature – it vents the air from the brake lines faster than the foot valve alone can, which helps with quicker braking and prevents the brakes from staying partially applied. It sits in the air brake system, usually somewhere between your foot valve and the air brake chambers. It's a key component in how your air brakes work, taking that initial signal and distributing the air pressure to actually do the stopping. Think of it as a middleman, stepping up the power. It's most commonly found on trucks and trailers, of course, anything using air brakes. Well, if this valve fails, you’ll notice if you're trying to stop. You might get a delayed response when you hit the brakes, or they might not apply fully. It can also cause the brakes to drag a little, which wastes fuel and wears down your brake components faster. A failing relay valve is a safety issue, plain and simple. You want to address it as soon as you suspect a problem. We carry a good selection of them, and you can also find options at places like Fixparts Online, just to compare. Getting the right one is important, so make sure you have your vehicle’s information handy when you order. Wabco stands behind its products: Relay Valve (MPN PRO0110040) has a 12-month warranty!
