Question by: Roy R on Dec 29, 2025, 11:42 AM
Reckon this check valve can handle a steady 5000 PSI in a hydraulic setup? Just want to make sure it won't give out on me.
Answer by: Customer Support on Dec 31, 2025, 8:38 AM
This steel check valve is rated to handle up to 5000 PSI maximum operating pressure, so it should be able to handle that pressure in a non-shock hydraulic system.
