Description
Constantly increasing demands on quality, accuracy, productivity, comfort, ease of operation and service place ever higher demands on operating and manufacturing equipment. These high demands can only be achieved with a more precise adjustment of the physical variables such as temperature, pressure, force, speed, torque etc. to the respective operating conditions. The stepless adjustment of the physical variables is of decisive importance here. Proportional valves open up the possibility of varying a medium depending on an electronic input variable. The linkage with electronics improves the accuracy and expands the fields of application. For example, a pressure regulator must be usable for many pressure ranges without manually adjusting the pressure. The proportional valve regulates the output pressure in a closed control loop proportionally to the specified setpoint signal. The output pressure is thus constantly compared with the desired setpoint and continuously adjusted - always depending on the current parameters.
