Difference between hydraulic pressure relief valve and pressure reducing valve

Question

Accepted Answer

Hydraulic pressure relief valve releases excess pressure while pressure reducing valve maintains a constant pressure.

Hydraulic pressure relief valve is used to protect the system from overpressure by releasing the excess pressure.
Pressure reducing valve is used to maintain a constant pressure in the system by reducing the incoming pressure.
Hydraulic pressure relief valve is typically set to a higher pressure than the system operating pressure.
Pressure reducing valve is typically set to a lower pressure than the incoming pressure.
Hydraulic pressure relief valve is usually located at the pump outlet or in the system's high-pressure line.
Pressure reducing valve is usually located at the system's inlet or in the low-pressure line.
