Inline Check Valves

Inline check valves, also called cartridge or poppet checks, pack a spring and disc into a compact threaded or barbed body that installs in any orientation, including straight-down vertical runs where a swing check will not work. They are the workhorse of chemical metering and dosing systems, small pumps, and instrumentation. Apex Flow Solutions stocks inline check valves from 1/8 in. up in brass, 316 stainless, and PVC, sold one at a time with no minimum.
