Wabco 4750090100 Pressure Reducing Valve

Description

The Wabco 4750090100 Pressure Reducing Valve is a critical component within air brake systems, designed to regulate and reduce air pressure. It is commonly used in commercial vehicles and trailers to ensure consistent and safe braking performance. This device maintains a stable downstream pressure, protecting sensitive components from excessive pressure, and ensures optimal brake function even with fluctuations in the primary air supply. It measures 66 x 73 x 82 mm and features M12 x 1.5 port threads. It operates within a temperature range of -40°C to +80°C and has a maximum operating pressure of 10.0 bar.

Key Features & Benefits

This valve takes the high – pressure air from your truck's air compressor and lowers it to a safe, usable pressure for things like the trailer brakes, or auxiliary systems. Basically, it steps down the air pressure. It has a couple of different settings you can adjust to get the right amount of pressure where you need it. Some have a priority feature too, so it ensures the tractor protection systems always get enough air first, even if you're running other air – powered equipment. Think of it as a regulator for your air system. Your air compressor makes a lot of pressure, but you don't want that much going to everything, especially trailer brakes. This valve sits in the air line and controls how much air gets through. It’s typically found in the air supply line going to the trailer or to other air accessories.

Symptoms, Risks & Replacements

It's really vital for safety and proper operation. Too much pressure to the trailer brakes, and you risk locking them up. Too little, and they won’t stop you effectively. It acts like a shield protecting your components from damage. You’ll notice if this valve fails because your trailer brakes might not apply correctly, or you could have issues with air horns or other air – powered accessories. If it sticks open, you might even get over – pressurized components. You can find these pretty easily at places like Fixparts Online, and it's a part you really don't want to run without a functioning one.
