got a Concentric GC8000 power unit kit, is this the right check valve for it?

Built for the Concentric GC8000 and GC8001 Series power unit kits, the GC8001 Series JBS Single PO CHECK is the matching check component for those kits.

Question by: Peggy R on Jan 10, 2026, 8:38 PM

what exactly is a "PO check" on one of these power unit kits, and what's it doing in the system?

Answer by: Customer Support on Jan 12, 2026, 6:38 AM

A pilot-operated check valve holds load pressure in one direction and only allows flow back through when a pilot signal tells it to open. On a DC hydraulic power unit like the GC8001 series, that means your cylinder or actuator stays put when the pump isn't running. No creep, no drift. It's a pretty common setup on lift and dump applications where you need the load locked in position between cycles.
