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.
