Español1. Switch action
The opening and closing actions of the double-acting cylinders are all driven and executed by the air source; the venting is open, the venting is off, and the air is cut off to maintain the original position; the single-acting opening action is driven by the air source, and the closing action is spring reset.

2. Type
Single-acting points: normally open and normally closed.
Normally open type is divided into: ventilated closed, cut off air open; normally closed type: ventilated open, cut off air closed.
Single-acting points: normally open and normally closed.
Normally open type is divided into: ventilated closed, cut off air open; normally closed type: ventilated open, cut off air closed.
3. Function
Single-acting has a single function than double-acting. For example, double-acting can be connected to a three-position five-way middle seal, medium voltage and so on to achieve safety functions, but single-acting cannot achieve this function.

4. Working principle
Double action: When the air source pressure enters the cavity between the two pistons of the cylinder from the air port, the two pistons are separated and move toward the ends of the cylinder. The air in the air chambers at both ends is discharged through the air ports, and the two piston racks simultaneously drive the output shaft The (gear) rotates counterclockwise.
Single-acting: When the air source pressure enters the cavity between the two pistons of the cylinder from the air port, the two pistons are separated and moved toward the ends of the cylinder, forcing the springs at both ends to compress, and the air in the air chambers at both ends is discharged through the air port, and the two pistons are discharged at the same time. The rack synchronously drives the output shaft (gear) to rotate counterclockwise.
