Proportioning and Residual Valves


Brake System Diagram
Why Do You Need Pressure Valves In Your Brake System?

The new generation of adjustable proportioning valves combine the latest refinements to deliver precise pressure metering and strength from a compact forged billet design. Pressure adjustments range from 100-1000 PSI and provide for a maximum decrease of 57% in line pressure, the most of any available valve. Adjuster knob with fine thread tuning provides precise pressure adjustment. This adjustment lets you fine tune the front to rear braking balance by proportionally decreasing the rear brake line pressure.

Two pound residual pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in both disc and drum brake systems. The two pound valve is used in disc brake applications - especially where the master cylinder is mounted below the horizontal plane of the calipers and fluid drain-back occurs from gravity and vibration, thereby causing excessive caliper piston retraction and a longer brake pedal stroke. The minimal two pound residual pressure prevents fluid from flowing back without causing the brakes to drag. Residual Pressure Valves are made from billet aluminum and color coded for easy identification.

Ten pound residual pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in drum brake systems. With drum brakes, a ten pound valve is used to compensate for return spring tension and maintain wheel cylinder sealing in the drums. Residual Pressure Valves are made from billet aluminum and color coded for easy identification.
