Wabco 4630372010 4/3 Way Solenoid Valve Ng90

Description

The Wabco 4/3 Way Solenoid Valve Ng90 is a critical component within air brake systems, designed to control the flow of compressed air to actuate brakes and other pneumatic devices in commercial vehicles. This valve is commonly found in trucks, buses, and trailers where reliable and precise air control is essential for safe operation. The 4/3 configuration indicates that the valve has four ports and three positions, allowing for versatile control of air flow. With its locking function and OE specification, this solenoid valve ensures consistent and dependable performance under demanding conditions. Its robust construction and precise engineering contribute to extended service life and reduced maintenance requirements. Dimensions are 40 x 62 x 94 mm. MPN is 4630372010.

Key Features & Benefits

This valve basically controls the flow of compressed air in your air brake system. The “4/3 way” part means it has four ports for air to enter and exit, and three positions it can switch between – it can block air flow, let air flow directly through, or exhaust air. It's electrically operated, so when the signal comes from your braking system, the valve quickly opens or closes to apply or release the brakes. It’s a switching station, deciding where the air goes. Think of it as a critical part of the brains behind your air brakes. It's usually used in things like trailer control, parking brakes, or auxiliary brake systems. It receives a signal and tells the brake chambers to either inflate (apply the brake) or deflate (release the brake). It’s not the whole brake system itself, but a key component within it. You'll usually find these on larger vehicles – trucks, buses, trailers, that sort of thing.

Symptoms, Risks & Replacements

Without a functioning solenoid valve like this, your air brakes won't operate reliably – or at all. If it fails, you could experience a loss of braking power, which is obviously really serious. It acts like a shield protecting your ability to stop. You’ll notice if it’s going bad, often by slow brake response, brakes not fully releasing, or even the brakes locking up. It's a safety item, so you definitely want to keep it in good shape.
