How Do Automotive Proportioning Valves Work?

Read Time:2 Minute, 24 Second

If you’re a car enthusiast, you’ve probably heard of Automotive Proportioning Valves. However, you may not be entirely sure what they are or how they work. While they are an essential part of a car’s brake system, they can fail in certain circumstances. Some examples of these issues include nose diving when applying the brakes hard, locking up the rear wheels, and a lack of brake response when driving on wet surfaces. Here are a few ways to determine if your car has a proportioning valve problem:

Global Automotive Proportioning Valves Market Report 2018-2023 – Detailed Analysis

North America is expected to hold the largest share in the market during the forecast period. Stringent emission regulations and an increasing number of electric vehicles are anticipated to fuel growth in this region. In addition, a growing demand for plug-in hybrid electric vehicles is expected to further fuel the market in the future. Furthermore, sales of mini-electric vehicles rose 138% in 2018 compared to the previous year, which will spur growth in the region.

To replace the proportioning valve, dismantle the vehicle’s mounting bolts and remove the old one. Afterward, drop the new proportioning valve into the pan. Be sure to torque it to 30 inch pounds before installing the new one. Next, connect the hydraulic lines to the intake and exhaust ports on the new valve. Then, tighten the lines using a line wrench. Be sure to use caution when installing the hydraulic lines as any slight bending may crack the brake fluid.

The automotive proportioning valve is an important part of braking system. They connect the master cylinder to the rest of the braking system and reduce the pressure in the brake fluid. Using the automotive proportioning valve, the force of the brakes can be more evenly distributed throughout the vehicle. This prevents the rear tyres from locking. As a result, the market for automotive proportioning valves is predicted to increase during the forecast period.

A proportioning valve uses the laws of fluid pressure to distribute input forces to the front and rear brakes. By increasing the spring preload on the piston, the valve will be able to handle more line pressure before closing. Similarly, decreasing the spring preload will trigger the valve to close at lower pressure, moving the knee point further down the graph. This way, when the vehicle is braking, its brakes will always be balanced out.

A proportioning valve controls the pressure on the rear brake circuit and is located between the master cylinder and the rest of the brake system. A proportioning valve is essential for safe and effective braking. Without a functioning proportioning valve, the rear brakes may experience excessive pressure during rapid deceleration. This is especially important in lightweight vehicles. If the proportioning valve is not working correctly, the rear brakes can lock up, resulting in a loss of control.
