Reliable Flow in a Companct Package.

In vacuum and pressure systems, even the smallest amount of backflow can create major headaches. That’s why the Series ICV Inline Check Valve is engineered to stop reverse flow before it starts—with bubble-tight sealing at extremely low differential pressures.

Compact and easy to integrate, the ICV features a floating poppet and fluted retainer to maintain laminar flow, while its metal-to-metal stop delivers a long, reliable service life. Whether installed horizontally or vertically, it seals with precision—every time.

The ICV is available with nominal crack pressures of 0.15, 1, or 3 PSIG and can handle everything from full vacuum up to 800 PSIG, with proof pressure ratings up to 1200 PSIG. It performs with zero leakage at back pressures above 0.5 PSIG, and operates dependably across a wide temperature range—from -80°F to 375°F.
