Residual Pressure Valve

Wilwood's two, four and ten 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 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. Four pound valves can be beneficial in high vibration brake sytems such as off-road or dirt circle track racing. 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. Valves with fittings are supplied with two 1/8-27 NPT to 3/8-24 inverted flare female fittings that will fit most domestic 3/16th hard brake lines.

Wilwood’s next generation Residual Pressure Valves (RPV) deliver the same outstanding performance and reliability as their previous versions but in a sleek new, fully detail-machined design. The valves are available with 2 or 10 pound pressure ratings to maintain minimal line pressure and prevent excessive pedal travel during initial engagement on disc or drum brake systems. Valves with 1/8”-27 NPT female ports are available individually, or packaged with two 3/8”-24 inverted flare female adapter fittings to accommodate 3/16” double flared hard lines. The valves are precision machined from billet aluminum and color coded with red or blue bright anodizing for easy identification.

Wilwood is excited to introduce a new 4 PSI-rated Residual Pressure Valve (RPV) to their line of pressure and flow controls. The 4 PSI Gold valve adds an option between the existing 2 PSI Blue and 10 PSI Red valves on disc brake systems where extreme shock loads, hard vibration, and suspension component flex can contribute to excessive caliper piston retraction and pad knock back.
