3280 2/2-Way Proportional Valve

Brand: Burkert Fluid Control Systems

The direct-acting proportional valve of Type 3280 is used for dosing of liquids and gases in closed or open control loops.

The valve features a linear stepper motor as actuator. The integrated electronics simplify 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.

Type 3280 is available as standard ON/OFF or proportional valve, as version with integrated positioner and as version with integrated process controller.
