Key Features & Benefits

This valve basically controls the air supply to your trailer’s brakes. It's got a couple of main jobs. It normally allows air to flow to the brakes, letting you slow down and stop like you're used to. But – and this is the important part – if there's a big drop in air pressure somewhere in the system – like a broken air line, or a leak – it cuts off that air supply. It also has a manual pull cable, so the driver can shut off the air supply themselves if needed. Think of it like a safety net for your braking system. It’s a key part of your trailer’s air brake system, working alongside your air compressor, air lines, and brake chambers. It sits between the tractor protection valve and the trailer supply line. It’s designed to protect the trailer brakes from running away if something goes wrong with the air supply. It doesn’t make the trailer stop, but it prevents a runaway situation. It’s especially important for heavier trailers.

Symptoms, Risks & Replacements

Well, imagine a situation where you lose air pressure while you're hauling a big load. Without this valve, the trailer brakes could release unexpectedly, and you’d lose control. This valve acts like a shield, preventing that from happening. You’ll notice if this valve fails because your trailer might not brake properly, or you might get a warning light on your dash. You can find these parts pretty easily – we stock a good selection here, and places like Fixparts Online are good resources too. It’s one of those things you don’t think about until it’s a problem, but keeping it in good working order is crucial for safety.
