We developed and started producing AVDs in a basic version in autumn 2017. The range of models was initially limited to the most general mixing valve actuator and basic mounting accessories. In 2019, the range of actuators and their accessories has been extended to the complete family.
AVD motor drives are now available as 2-point, 3-point, universal 2-point, 3-point and modulating with analogue (0-10 V, 0-20 mA) or PWM signals. The supply voltage is selectable between 24 VAC or 230 VAC. Motor drive speeds are standard: 15, 30, 60, 120, 240 and 480 seconds. The mounting accessories now also include ISO 5211 ball valve accessories.
