Valves weigh only 5.2 ounces and have two 0.25 "side mounting holes at a distance of 1.00" from each other. Standard import and export is 1 / 8-27 NPT.

Proportioning Valve

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 150-1200 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. Valves weigh only 5.2 ounces and have two .25” side mounting holes spaced 1.00” apart. Inlet / outlet ports are 1/8-27 NPT and valves 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.

Rotating the know in (clockwise) will incrementally increase line prressure, up to full pressure. If the
range of adjustment in the valve is not sufficient to properly balance the vehicle’s bias, changes to other
components within the system may be necessary

The knob rotated all the way out (counter-clockwise) will provide a maximum pressure reduction of
57%
