PRODUCT DESCRIPTION
Proportioning Valve - Product Overview
The new generation of adjustable proportioning valves combines the latest innovations to provide precise pressure dosage and high resistance thanks to its compact forged design. The pressure adjustment range is from 150 to 1200 PSI and allows for a maximum 57% reduction in line pressure, the highest of any available valve. The fine-threaded adjustment knob provides precise pressure regulation. The valves weigh only 147 grams (5.2 ounces) and feature two 6.35 mm (0.25") side mounting holes spaced 2.54 mm (1.00") apart. The inlet and outlet ports are 1/8-27 NPT and the valves are supplied with two 1/8-27 NPT to 3/8-24 inverted flare female adapters, compatible with most domestic 3/16" (3/16") rigid brake lines.
