got a harvester that needs a check valve, is this 4CK301S3 the kind folks run on mobile equipment?

Answer by: Customer Support on Aug 30, 2025, 1:05 PM

Common use for it is on harvesters, refuse haulers, and other mobile or industrial hydraulic setups. It is a 4CK30 Series poppet style check valve, so it fits that one way flow, backflow blocking role those machines usually need.
