Converting pneumatic pressure to hydraulic pressure (equivalent pressure) solves cylinder problems occurring due to the compression characteristics of pneumatic pressure. • Constant-speed operation is possible with load fluctuations. • Solves the problems of sticking and slipping associated with low-speed operation. • Intermediate stopping and skip movement possible. • Suitable for slow operation of a rotary actuator. Integrate a converter and a valve unit in a compact configuration. • Possible to select 4 types of valve units for applications. • Possible to connect a converter and a valve unit independently. Wide range of series in terms of converter capacity and valve unit flow rate control capability. • Compatible with cylinder bore sizes up to 0300. • Operation at a piston speed of 180 mm/sec with a size 08O cylinder bore.

Selection Procedure Step (1) Select the bore size of air-hydro cylinder First of all, select a bore size from data (D) <Theoretical Output Table>. When making a selection, the ratio between the theoretical output and the load should be 0.5 or less. Step (2) Select converter_ Select the nominal diameter and the effective oil level stroke from data (A), <Cylinder Displacement and Converter Capacity Diagram>. When selecting a converter by its nominal diameter, the converter's oil level speed should be Step (3) Select required function for valve unit Select a model from data (B), <Converter and Valve...

Air-hydro Unit Series CC Data (D) Theoretical Output A Caution on Circuit Construction Skip valve 1. When using a skip valve, the maximum allow- able ratio between the high speed and the low speed is approximately 3:1. If this ratio is too large, air bubbles could form due to cavitations, and could lead to the conditions described in Product Specific Precautions (page 936). 2. If the skip valve of an air-hydro unit with skip valve is operated, because it is not equipped with a speed control valve, the fast-forward speed will be determined by the model, piping conditions, and the actuator used....

Air-hydro Unit The air-hydro unit consists of a converter and a valve unit that are compactly integrated. It converts air pressure to an equivalent hydraulic pressure, and this hydraulic pressure is used for operating an actuator, thus solving the problem that is associated with the compression characteristics of air. Thus, in spite of using pneumatic equipment, it performs similarly to a hydraulic unit, operating at a constant speed during starting or in the presence of load fluctuations, and at the same time solving the problems of sticking and slipping associated with low speed operations....
