Bias Proportioning valves are mostly used
in a car’s hydraulic braking system and help to manage fluid pressure. Over the
years, they have gained a lot of popularity in the automotive industry and are
highly demanded performance upgrades.
Situated between the master cylinder and
other parts of the braking system, these valves are responsible for efficient
working of the braking system regardless of the driving conditions. This
ensures safety and reliability of the vehicle. Proportioning valves are crucial
to high-performance vehicles as they enhance braking performance.
The main purpose of the valve is to manage
the amount of pressure that is applied on the axles and the time it has to be
applied. There are three types of valves available today; master cylinder
mounted, load sensing and combination valve mounted.
If you brake your car while racing and all
wheels lock up, your car can end up skidding to the edge. For stability
purposes, a driver would want the rear wheels of a car to have less strength
than the front wheels to stay in control while braking. This will allow the
driver to take sharp cuts while driving.
Valves help control the bias between the
front and rear wheels so that when you brake, the front wheels lock up while
the rear wheels offer appropriate amounts of resistance to ease turning or
stopping without drifting. The high pressure caused by rapid deceleration of
the car can be controlled with these valves as they help reduce the pressure on
the rear wheels.
Pickup trucks and other lightweight
vehicles opt for bias proportioning valves to prevent rear wheel lockups during
braking as the rear of these vehicles is typically lighter. Today the modern
electronic brake systems handle the function of valves, improving performance
and efficiency drastically.
