Product Questions & Answers

these check valves rated high enough for heavy equipment use, like a commercial harvester runnin all day?

Question by: Daryl W on Jan 4, 2026, 6:18 AM

At 350 bar (5000 psi) and a flow rate up to 227 liters per minute (60 USgpm), these valves are built for exactly that kind of work. Harvesters are actually one of the listed applications for the 4SK90 series, so you're in solid territory there. The poppet-style design helps keep efficiency up even under sustained demand, and the low spring settings support smooth operation without fighting the system.

Reckon this check valve can handle continuous use in a hydraulic system?

Rated to 350 bar (5000 psi) and a flow rate of 90 liters per minute, this poppet-style check valve is built for efficiency, even with lower spring settings. Just make sure your specific application doesn't exceed those limits.
