■ How to select orifice bore ■ Select orifice bore by the following method, when controlling cylinder speed with Speed Controller Constant Flow. ① Use the following calculation formula and find an necessary air flow rate in order to control cylinder at desired speed. (Calculation to find air flow rate) P ＋ 0.1013 D2 × L 　 Q ＝ 4.7 × 10-5 ×────×────── t 0.1013 　 Q ＝ Air flow rate (l/min(ANR)) 　 D ＝ Cylinder tube I.D.(mm) 　 L ＝ Cylinder stroke (mm) 　 t ＝ One-way stroke time (sec) 　 P ＝ Operating pressure (MPa) ② Use the chart of Flow Characteristic. Select 2 or 3 orifice bores which are closer to...

Common Safety Instructions for Controllers Before selecting or using PISCO products, read the following instructions. Read the detailed instructions for individual series as well as the instructions below. Warning 1. Some products have an air direction to control. Make sure to distinguish the direction by marking on the products. Installing the product with the wrong direction may cause personal injury or property damage. 2. Avoid any load on PISCO products such as a tensile strength, twisting, bending, dropping and excessive impacts. These may cause damage to the products. 3. Locknut needs to...
