Hydraulic pressure continuous operation range is which?

Hydraulic pressure continuous operation range is which?

• A. 1200-1400 psi
• B. 1600 psi
• C. 1200 psi
• D. 1400-1600 psi

Answer: (D)

Continuous operation range shows the pressure band the hydraulic system can run at for an extended period without overheating or causing wear beyond acceptable limits. It’s a range because real work isn’t at a single fixed pressure—you swing between loads that rise and fall, and the system must handle that continuously. The correct range is 1400-1600 psi, which reflects the level near the system’s sustained capability: you can operate within this band for ongoing use without pushing into limits that would require cooling or risk damage. The other options either give a single pressure value or a lower range, which doesn’t capture the sustained operating capability the question targets.
