The direct-acting Type 3285 motor valve is suitable for dosing liquids and gases in closed or open control loops. The valve is driven by a stepper motor. The integrated electronics assembly simplifies the process integration; additional actuation modules are not necessary. The engine does not need any energy to maintain a certain valve opening. This feature can reduce the energy consumption of a plant dramatically and therefore make it more efficient. Type 3285 is available as an on/off valve or proportional valve by default, as a variant with integrated positioner, and as a variant with integrated process controller.
