The direct-acting motor valve is used for dosing of liquids and gases in closed or open control loops. The valve features a stepper motor/dc motor as the actuator. The integrated electronics simplifies the process integration; additional actuation modules are not necessary. The motor’s power consumption to hold a specific opening position of the valve is zero. This key feature can reduce the energy consumption of a plant dramatically and thus make it more efficient.Valve is available as a standard ON/OFF or proportional valve, as a version with integrated positioner and as a version with integrated process controller.
