The VAEM solenoid valve controller supports multi-head pharmaceutical manufacturing and laboratory micro-dispensing applications that require high speed and a low coefficient of variation (CV). The compact, energy efficient VAEM provides individualized control and calibration for up to eight solenoid valves. It can open a valve in <2ms. Rapid, precise control of the valve decreased CV to less than 0.5% in laboratory benchmark testing. Users can easily, quickly calibrate flow through individual channels, improving precision in multi-head systems.
The VAEM employs a hit-and-hold strategy to lower energy consumption. A short burst of high current hits the open position, then the VAEM switches to a minimum current to hold the open position for a specified time. Using current rather than voltage to control valves diminishes heat buildup and maintains specified flow.
