  • Lightweight and Easy to Install




All AES patented Piston Operated Mixers (POM-30 to POM-100) can be equipped with this option. It consists of an electric actuator, mounted on top of the POM valve, and a controller with PID characteristics. The controller receives a 4-20 mA signal from a calorimeter, gravitometer (such as the GraviBlend™-3), or oxygen analyzer, and compares this signal with a pre-set value, representing the correct mixture. If deviations are detected, the actuator changes the rotational position of the piston in the POM valve, thereby effectively correcting the mixture to meet customer requirements.
