At Festo, servo-pneumatics stands for controlled pneumatic positioning technology. Servo-pneumatics is always a system consisting of a cylinder with a displacement encoder, a proportional directional control valve, and a position controller. With a servo-pneumatic system, a pneumatic cylinder can be moved to a preset target position in a position-controlled manner or generate a preset target force in a force-controlled manner. Servo-pneumatics is a “soft” positioning technology because air is a compressible drive medium. When the drive is in a controlled position, it can be pushed away by a correspondingly large external force. These systems are good value for money, especially for moving weights over 10 kg.
