The direct-acting motor valve type 3281 is particularly suitable for dosing liquids

and gases in closed or open control loops. The valve is driven by a linear 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

3281 is available as a variant with integrated positioner, as well as a variant with

integrated process controller.
