The G-Series Solenoid Operated Directional Valves incorporate electronic circuits o enable adjustment of the spool shifting time. A special spool shape that minimises shock is used, shocks caused by the
actuator starting and stopping, as well as vibration due to oil hammering. The shifting time of conventional Solenoid Operated, Shockless, and Directional Valves is constant and cannot be adjusted. 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 machine.
