The design of pneumatic and hydraulic drives with significantly enhanced dynamic characteristics is important in developing modern automatic control systems for compressor and vacuum machines. The actuators typically consisting of a drive and a control device (valve, shutter) are used as elements of the control system. Such control devices generally have considerable unbalanced torques that the drive should overcome. The study shows that shaped throttle shutter and louvered shutters make it possible to significantly reduce the unbalanced torques. New shutter shapes are considered. When such shutters are installed in rectangular cross section pipes, the use of hydraulic and pneumatic drives with reduced power and force is appropriate. It leads to a significant improvement in the quality of control processes in vacuum and compressor machines and installations.
