Swing cylinders and hydraulic work supports are very sensitive to oil flow rate. To ensure safe and reliable function of these elements, the maximum oil flow rate specified in the catalog pages and product instructions must not be exceeded. If there is a risk of high flow rates, use flow control valves to limit the flow rate.

The clamping sequence must be set up so that work supports are operated only after the workpiece has been firmly positioned against the locators. An exception is a work support directly opposite a clamping cylinder. In this case, the work support should be brought to full pressure before the clamping cylinders actuate. This sequence is accomplished via either modular (solenoid) valves or a sequence valve, as depicted in the diagram.
