This proportional control system is a combination of a piston operated diaphragm valve with a uniquely formed stainless steel body and an electropneumatically operated, Type 1067 positioner. The positioner consists of three main parts: the valve stem position pickup, the electropneumatic control system and the micro-processor electronics. The valve stem position pickup, a linear potentiometer connected to the valve stem, feeds back the actual stem position to the positioner electronics. The micro-processor electronics compares the actual stem position to the set point given by a standard signal (4-20mA, 0-10V,...). In the case of a position difference, the electropneumatic control system corrects the stem position until the set point is reached.
