Question by: Scott S on May 24, 2025, 7:20 AM
Running a refuse hauler and need a check valve that can hold up to real pressure. This Vickers 4CK901SV rated for anything serious, or is it more of a light-duty part?
Answer by: Customer Support on May 25, 2025, 3:13 PM
For refuse hauler work, this one holds its own. It's rated up to 350 bar, which is 5000 psi, and handles flow up to 227 liters per minute, or 60 US gallons per minute. That's a solid ceiling for most mobile hydraulic setups. The poppet-style design keeps backflow in check and helps the system maintain pressure where it needs to. Low spring settings also mean it responds quick without requiring much pressure drop to open, which matters when you're cycling the system repeatedly through a full shift.

Reckon this check valve can handle a hydraulic system running at a steady 4500 psi?
Answer by: Customer Support on Aug 3, 2025, 7:26 PM
This Vickers valve is built to handle pressures up to 5000 psi (350 bar), so 4500 psi should be well within its operating range. Just make sure the rest of your system components are rated accordingly.
