Idex – Flow Regulating Valves – Check Valves
In many applications, there is a need to limit the fluid flow to one direction. Check valves are the perfect solution for this need. Several versions are available, including our standard check valves, our non-metallic check valves, and even some specialized luer-based check valves. Check Valves are designed to effectively deliver a low cracking pressure. Most of our Check Valves connect directly to any 1/4-28 flat-bottom port. We created this unique design to eliminate the need for additional tubing cuts and connections to install traditional check valves. They accept fittings with 1/32 inches, 1/16 inches, 1/8 inches or 1.0 to 3.0 mm outer diameter tubing.
Available Models
Inline Cartridge Check Valves are designed to limit flow in one direction and deliver a low cracking pressure. Ideal placement for these valves would be on the effluent side of the column to prevent post-column derivatization agents from flowing back and poisoning the column if the HPLC mobile phase pump were to shut down.
