Recommended Viscosity and Oil Temperatures 2 Viscosity ranging between 15 - 200 mm /s
(77 - 927 SSU). Oil temperatures between -15/+60°C (5 - 140°F).
Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above.
Control of Contamination Due caution must be paid to maintaining control
the maximum flow rate c an be adjusted by use of the valve with stroke adjustment screw of optional extra.
Here, take care to keep the HALT signal on for longer than 0.1 second.
The G-Series Solenoid Operated Directional Valves incorporate electronic circuits to enable
adjustment of the spool shifting time. As the shifting time of the G-Series valves can be adjusted,
it can be set at an optimal level to minimise shocks to the m achine.
The min. flow rate gets to "0" after about 60 seconds following the OFF T.
If the HALT functions a re not used, set the minimum adjusting volume to zero.
The HALT functions are not applicable to the spool function "2B7".
over contamination of the hydraulic fluids which may otherwise lead to breakdowns and shorten the life of the valves.
Please maintain the degree of contamination within NAS 1638Grade 12. Use 25 μm or finer line filter.
"G" Series Shockless Type Solenoid Operated /
In a hydraulic circuit where a pilot controlled check valve is used, there is a possibility
that the knocking will arise on t he pilot controlled check valve during deceleration
depending on the largeness of load inertia, the state of piping and t he length of "Off T" time etc.

Instructions Adjustment of maximum flow rate The G-Series Solenoid Operated Directional Valves
Fluid Types Any type of hydraulic fluids listed in the table below can be used.
How to use HALT functions The HALT functions are used to drive the actuator at a low speed to the stop
position while keeping a slight flow after OFF T. A flow rate (min. flow rate)
during a low-speed operation can be set with the minimum adjusting volume
(The minimum adjusting volume is common for SOL a and b. Individual setting is not possible for SOL a and b.)
When HALT signal i s on, the min. flow rate becomes zero and the actuator stops.
cannot be adjusted for maximum flow rates. To adjust maximum flow rates, use flow control valves.
