Total clamping force Diaphragm clamping force Additional clamping force applied by the actuating cylinder IMPORTANT: Pressure regulators have to be installed in Line A + B The total clamping force (FG) is the total of the diaphragm clamping force and the clamping force (FZ), created by the draw pull (F1) of the actuating cylinder. Thus the clamping force FG can be regulated by adjusting the pressure of the actuating cylinder. Advice: Please note, it is important, that the cylinder force for pushing and pulling can be set to different values independently.
