a must for this brake system to function properly
a pressure reduction device
a simple valve that limits the pressure to the rear brakes
A valve in the brake hydraulic system that reduces pressure to the rear wheels to achieve better brake balance.
Valve used to balance or divide the air supply between the aeration system and the discharge manifold of a foam system.
A proportioning valve is a valve that relies on the laws of fluid pressure to distribute input forces to one or more output lines. A proportioning valve can increase or decrease forces for each output, depending on the cross-sectional surface areas of those output lines.
