The Wabco PRO0110070 Relay Valve is a critical component within air brake systems, responsible for efficiently relaying and regulating air pressure to the service brakes. This valve is primarily used in heavy-duty vehicles, trailers, and buses to ensure reliable and responsive braking performance. It features M22 x 1.5 and M16 x 1.5 port threads for secure connections and operates within a temperature range of -40°C to +80°C. The device operates at a 1:1 regulating ratio, with a predominance of 0.20 bar and a response pressure of 0.20 bar. Its pressure reduction version and integrated silencer contribute to a quieter and more controlled braking system. The valve's dimensions are 150 x 125 x 125 mm and its calculated volume is 2.3438. It is designed for a maximum operating pressure of 10.0 bar, and a maximum temporary pressure of 13 bar, mounted using 4x M8 bolts. 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. Advanced engineering: Relay Valve (MPN PRO0110070) comes with a 12-month warranty!
