Note: Max. flow means the limited flow which does not affect the normal function (changeover) of the valve.
1 Varies depending of the spool type. For the detail, see the “List of standard models and max. flow” for
DSG-03 Series Solenoid Operated Directional Valves (EIC-E-1002, Page 3 or 4 at 50 Hz rated voltage.)
2 Lever operating torque varies depending on the T-Line back pressure. See the figure below.
3 If the T-Line back pressure exceeds 70 Kgf/cm2, directly connect the drain port to the reservoir.

Instructions
Avoid connecting the tank Port “T”
to a line with possible surge pressure.
Pressure Drops
The pressure drop characteristics are based on the following conditions: viscosity of the fluid:35cSt
Specific Gravity: 0.850
For any other viscosity, multiple the factors in the table below.

For any other specific gravity (G'), the pressure drop ( P') may be obtained
from the formula below.
P' = P G'/G where, P is a value on the following chart and G is 0.850.
