Design: At PJS we do one thing only and that’s create awesome products that work better than anything else on the market. Our Pro Flow coolant flow valve is a glaring example of metalworking artistry. We designed and manufactured these flow regulators back in the 1990’s when they were promptly copied by several other unscrupulous outfits with little knowledge of how they actually work. We are now re-releasing our original and improved design to the industry with our name and reputation laser engraved into every one of them.
Constrtuction: Unlike the competition, we precision knurl an exclusive gripping surface on the outside of both elements for easy adjusting. No more using pipe wrenches and vise grips to adjust them causing ugly teeth marks in your custom parts, that’s for hacks and monkeys. The inner workings are constructed using stainless steel and corrosion proof Delrin nylon for years of trouble free service. We use Buna-N O-rings for high abrasion resistance and a watertight seal at all interfaces. The Pro Flow is designed with an extra long length extended range of operation for a broad range of opening pressures to allow tuners to find that perfect “sweet spot” no matter how low or high you need it to be.
Each Pro Flow regulator valve comes with a set of two super high quality Norma brand all stainless steel “formed” hose clamps for a perfect seal that doesn’t damage your expensive water lines by cutting or “extruding ” the hose through the perforated band like cheap hose clamps often do. And our exclusive Norma brand clamps are much stronger and resist breakage even when high torque is applied. Check out our hose clamps elsewhere on our website.
The Pro Flow is the absolute best coolant flow regulator on the market bar none. We know our competition has been making them for years, but why not, they didn’t have to spend money designing it, it was easier just to copy it. Now it’s time to buy one from the guys who designed it, refined it, perfected it, and proudly put our name on it. We’re PJS, it’s where integrity is built into everything we make.
