1. With dual electronically controlled solenoid valves, the effect of opening 1/2 coils at the same time and closing 1/2 coils at the same time is the same, both of which maintain the original state of the cylinder. The control parts on both sides of the dual electronic control are completely equal.
2. The advantage of dual control is that the cylinder can be operated in the extended or retracted state for a long time, and the solenoid valve does not need to be energized. If it is a single control solenoid valve, it can only ensure that the cylinder is not energized when extended or retracted. The power is different when returning. For example, your cylinder needs to extend for an hour, and then retract for an hour. If it is a single-control solenoid valve, it must be powered on for an hour at one time. This consumes electricity and the solenoid valve may It will be burned due to heat, but the dual-control solenoid valve can cut off power as long as the cylinder is in place, and the cylinder remains stationary.
