11.3.2 Components of a Hydraulic Solenoid Valve Bank
a) 4/2 Directional Valve Element
• Size 6
• Maximum operating pressure 310 bar [4500 psi]
• Maximum flow 30 l/min [7.9 gpm]
• Port connections G 3/8 - SAE6
b) Pressure Reducing and Relieving Valve (PRV)
Reduce the oil pressure to actuator in order to prevent it from damage
due to unexpected high pressure. The maximum working pressure
of the PRV is 350 bar (5076 PSI) and its adjusted pressure range is
28-80 bar (406-1160 PSI). In other words, the pump pressure to the
valve bank is not the main concern since the maximum pressure to
the actuator is 80 bar, as long as the reduce valve is working properly.
The default setting of the PRV is 45-50 Bar (653-725 PSI), which is
safe for actuators.
