Fast response for large valve control 22/04/2014
It can be difficult to achieve the required levels of accuracy combined with fast positioning in process control systems that include larger valves. For example, where flow rates require valve sizes of 200mm and above enabling flows in excess of 200 m3/hr, pneumatic actuators are often fitted which provide significant positioning forces.
