(1) Nonadjustable pressure reducing valve (2) Adjustable pressure reducing valve | |
Pressure reducing valve (2) is factory set at a pressure of 2410 kPa (350 psi). Turn the adjusting nut in a clockwise direction in order to increase the pressure.
Pressure reducing valve (1) is nonadjustable.
The following examples are the hydraulic oil pressures in a normal operating system.
- The pressure in the hydraulic oil supply line should be a minimum of 2070 kPa (300 psi).
- The hydraulic oil pressure that is flowing from the pressure reducing valve (1) should be 2600 ± 100 kPa (380 ± 15 psi).
