Question by: Kurt C on Jun 13, 2025, 12:37 PM

Got a Vickers 5CK30 series check valve that needs replacing on my harvester. This the 1S2 model with the ball style and low spring setup?

Ball style with low spring settings, rated to 350 bar (5000 psi) and 30 liters per minute flow, yes, the 5CK301S2 fits that profile. It carries the Vickers sub-brand under Danfoss / Eaton and the supplier part number is 401AA00013A. If your original valve matches those specs and came off a harvester or similar mobile equipment, this is the correct replacement.

Will this handle fluids besides just regular hydraulic oil, or am I limited to a specific type of fluid?

Designed for mobile and industrial applications, this Vickers 5CK30 series check valve is commonly used with hydraulic fluids compatible with those systems. Consulting the specific fluid compatibility data sheets is a good idea if you're using specialized fluids.
