Type C: Introduction to the Principle of Median ClosureThe five holes are closed without power on, and the cylinder cannot be manually stretched. After power on, you can choose to open left and right first.Left side power on: P hole intake A hole, B hole exhaust S hole.Power on the right side: P-hole intake B-hole, A-hole exhaust R-hole.E type: Introduction to the principle of mid range exhaustIn the absence of power to both coils, the intake port is closed and the exhaust port is opened. The pressure on both sides of the cylinder is discharged through the two exhaust ports of the solenoid valve, and there is no pressure inside either side of the cylinder.Compared to the intermediate seal valve, this circuit can achieve a longer intermediate stop. In certain situations where the cylinder needs to move vertically and the intermediate stop time is long but the positioning accuracy is not very high, the intermediate release type can be considered.P-type: Medium pressure: In the case where neither coil is powered on, the intake port opens and the exhaust port closes. The pressure on both sides of the cylinder remains unchanged after the last coil is powered off, and continuous pressure is applied to ensure that the pressure on both sides of the cylinder is consistent with the pressure at the intake end.If the cylinder does not have axial external load force, then the piston remains balanced and can stop at the position during the stroke with high stopping accuracy. The prerequisite for achieving intermediate stop in this circuit is that the cylinder needs to be installed horizontally. Therefore, when high precision positioning of the cylinder is required and the cylinder can meet the requirement of no axial external load force, a medium pressure valve can be used in conjunction with a dual piston rod cylinder.
