The Wilwood knob-adjust proportioning valve combines a compact forged billet design with fine-thread adjustment to meter brake pressure between 100–1000 PSI and permit up to a 57% line pressure decrease for brake balance tuning. Weighing 5.2 ounces, it includes two .25" side mounting holes spaced 1.00" apart and uses 10mm x 1 bubble flare inlet/outlet seats, eliminating the need for tube nut adapters when installing tubing with 10mm x 1 bubble flare nuts.
