Description

The Wabco 9730111060 Relay Valve is a critical component within a vehicle's air brake system, responsible for relaying and maintaining air pressure to the service brakes. It is typically used in heavy-duty trucks, buses, and trailers to ensure reliable and efficient braking performance. This pressure reduction version maintains consistent air supply, enhancing responsiveness and safety. Its dimensions are 99 x 156 x 169 mm, and it features M22 x 1.5 port threads for connections, and 4x M8 mounting. The valve operates effectively within a temperature range of -40°C to +80°C, offering durability and consistent performance in diverse conditions. This OE specification relay valve provides precise air control, resulting in improved braking stability and reduced maintenance needs.

Key Features & Benefits

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.

Symptoms, Risks & Replacements

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.
