The Wabco PRO6430310 Pressure Limiting Valve is a critical component within air brake systems, designed to regulate and maintain safe air pressure. This valve is commonly used in commercial vehicles and trailers to ensure optimal braking performance and prevent over-pressurization. It features M16 x 1.5 ports and operates with a supply pressure of 11 bar, a delivery pressure of 7.5±0.2 bar, and a maximum operating pressure of 20.0 bar. Its precise construction and AM specification deliver consistent and reliable pressure regulation, contributing to enhanced safety and system longevity. The dimensions of this valve are 84 x 57 x 56 mm and 72 x 58 x 85 mm. This valve basically controls the maximum air pressure that goes into your brake system. It takes the higher pressure from your air compressor and reduces it to a safe level for the rest of your components – things like your air bags, actuators, and brake chambers. It’s a pretty simple idea, but really important for keeping everything working correctly. It doesn't make pressure, it just manages it, stepping it down to what the system needs. Think of it as a gatekeeper for your air brake system. It sits between the air compressor and the rest of the braking components. It ensures no single part is over – pressurized. It’s commonly found on trucks and trailers, anything that relies on air brakes to stop safely. Different vehicles might have it located in slightly different spots, usually somewhere along the air lines near the compressor or the first major components. Well, if this valve fails, you could have too much pressure going to parts that aren’t designed for it. That’s a recipe for blown seals, damaged actuators, or even complete brake failure. It acts like a shield, protecting the more sensitive parts of your air system. You’ll notice if it's failing – things like brakes dragging, unusually long stopping distances, or the air compressor running constantly. It's a relatively inexpensive part considering what it protects, and it's one of those things it's best to replace proactively if you suspect trouble. Fixparts Online has a good selection of these if you're looking for a replacement, and they often have diagrams that help you find the correct one for your vehicle. Designed for durability: Pressure Limiting Valve (MPN PRO6430310) includes a 12-month warranty!
