It operates with a calculated volume of 1.302, a charging pressure of 3.5 bar, and can handle a maximum operating pressure of 20.0 bar.

Key Features & Benefits

This valve basically manages air pressure in your spring brakes. It has two main jobs. First, it maintains a safe, constant air pressure to release your spring brakes when you need to drive. Second, and this is the important part, it protects the system from overpressure. Think of it like a safety valve on a hot water heater - it prevents things from getting dangerously high. It also prevents the air from completely bleeding out if there's a leak somewhere, meaning your spring brakes won't unexpectedly engage while you're moving. It's a key part of your air brake system, specifically designed to work with your spring brakes. Those spring brakes are a safety feature – they automatically apply if you lose air pressure. The protection valve ensures they stay off when you want them to, and kicks in to keep things stable if pressure drops or surges. It's installed in the supply line that feeds air to those spring brakes.

Symptoms, Risks & Replacements

Honestly, it’s critical for safety. If this valve fails, you could end up with your spring brakes partially engaged while driving – that’ll cause serious pulling and make it really hard to control the vehicle. Or, if it fails open, you might not have any emergency braking at all. You’ll notice if it's going bad – things like longer stopping distances, or the brakes feeling spongy. They’re relatively inexpensive to replace, and it's a small price to pay for keeping yourself and everyone else on the road safe. We can usually get these shipped pretty quickly through Fixparts Online, if you'd like me to check availability for your specific truck.
