Then, select a converter with a larger capacity. The converter will be o160 to 300. To obtain the capacity of the converter, multiply the cylinder displacement by approximately 1.5. Note) Select the nominal diameter of the converter so that the converter’s oil level speed does not exceed 200 mm/s. Data (A) Volume of Cylinder/Capacity of Converter Control Combined valve valve Without stop valve Without skip valve Stop valve Without control valve Throttle valve Flow control valve (With pressure compensation) Operating purpose Skip valve Operating purpose With stop valve With skip valve For applications that do not require speed control, as long as objects are moved smoothly. Or for applications in which a pneumatic speed controller suffices. (3 dm3/min or more) For applications that require a crawl speed control (0.3 dm3/min or more), provided that fluctuations caused by operating pressures and loads are permissible. For applications that require a crawl speed fluctuation control (0.04 to 0.06 dm3/min or more), and require an almost constant speed even when the operating pressure or the load fluctuates. In case only speed control is needed. Intermediate stops, step feed, emergency stops, and stop for service are possible. Intermediate stops, step feed, emergency stops, stops for service, double speed change are possible. Double speed change is possible.
