Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Hydro-pneumatic speed control cylinders according to standard ISO 15552 Series HP 3 Pneumatic actuation 3 | 1 Series HP • Bores Ø80 and Ø100 • Strokes up to 750 mm, every 50 mm • According to ISO 15552 standard HP series hydro-pneumatic speed control cylinders are made by combining an ISO 15552 pneumatic cylinder and an internal hydraulic circuit that controls the movement. They are ideal for all applications where precise and constant speed regulation is required in one or both directions. The cylinders are completely configurable thanks to the skip and stop valves and have the option of decentralized adjustment, and in this new version the design has been optimised and the hydraulic tank improved. All ISO fixing devices can be used (Intermediate trunnion, Ecolight series 1390 ... 1392).
