Wabco 9347050080 Quadruple Circuit Protection Valve

Description

The Wabco 9347050080 is a Quadruple Circuit Protection Valve designed for use in air brake systems. It protects the air system from bursting in case of failure and ensures operational safety. This valve features a robust design with calculated volume of 3.3903, charging pressure of 4.5 bar, and a maximum operating pressure of 13.0 bar. It includes M22 x 1.5 port threads and DIN 72585 electrical connections. The valve dimensions are 109 x 144 x 216 mm, and it meets OE specifications for reliable performance.

Key Features & Benefits

This valve essentially splits your braking system into four separate circuits – one for each wheel, generally. It takes the air pressure from your compressor and distributes it to the brake chambers at each wheel. But, and this is the key part, it also protects each circuit. If you spring a leak in one brake line – say, at a wheel cylinder or a brake hose – this valve is designed to isolate that leak. It prevents all the air from escaping from your entire system, which could leave you with little to no braking power. It's like having four independent mini – systems instead of one big one. Think of it as a central control point for your air brakes. It sits in the air line, usually between the compressor and the first set of axles. All the air heading to your brakes has to go through this valve. It doesn’t apply the brakes, it just manages the air supply to the parts that do. You’ll find it on most heavier vehicles – anything needing a robust air brake system for safety.

Symptoms, Risks & Replacements

This is a major safety component. If this valve fails, you lose that circuit protection I was talking about. You'll notice if it’s going bad – usually by a noticeable drop in air pressure when you apply the brakes, or a slow leak somewhere in the system. It could even lead to the brakes locking up on one axle. It’s not something you want to gamble with. A failing valve means a potentially dangerous situation. We carry these at Fixparts Online, and getting a new one is a lot cheaper than dealing with the consequences of brake failure.
