Why Kinko Check Valves Are Your Go-To for Backflow Prevention

It’s not just about stopping backflow—Kinko’s check valves do it reliably, without adding hassle to your operations. Here’s what makes them stand out from standard check valves:

1. 100% Backflow Prevention, No Exceptions

Kinko check valves use a precision-engineered swing or lift mechanism that responds instantly to flow changes. As soon as fluid tries to reverse direction, the valve closes tightly—creating an airtight seal that stops backflow completely. Unlike some cheap check valves that let small amounts of fluid slip through (leading to gradual pipe damage), Kinko’s design ensures zero reverse flow, protecting your pipes and system from start to finish.

2. Gentle on Pipes, Tough on Wear

We use high-quality materials like 304/316 stainless steel, brass, or cast iron for the valve body—all chosen for their durability and resistance to corrosion. The valve’s internal components are smooth and non-abrasive, so they don’t scratch or wear down your pipes over time. Plus, the quick-closing mechanism reduces water hammer (that loud bang from sudden flow stops), which is another common cause of pipe damage.

3. Easy to Install & Low-Maintenance

You don’t need a team of experts to set up these check valves—they fit standard pipe sizes (DN15-DN300) and require no complex adjustments. Once installed, they work automatically, with no need for manual operation. And since they’re built to last, you won’t have to deal with frequent repairs or replacements. Just install them and forget about them—they’ll keep protecting your pipes quietly in the background.
