The new generation of adjustable proportioning valves combines 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. This proportioning valve has six preset points actuated by moving a lever allowing racers to quickly adjust brake bias during a race. The lever “clicks” into the six positions for positive adjustment. Valves weigh only 6.1 ounces (lever), and have two .25” side mounting holes spaced 1.00” apart. Inlet / outlet ports are 1/8-27 NPT.
