The direct-acting motor valve of type 3285 is suitable for dosing liquids and gases in closed or open control circuits. The valve is driven by a stepper motor. The integrated electronics significantly facilitate process integration, eliminating the need for additional control modules. To maintain a specific valve opening, the motor requires no energy. This feature can drastically reduce the energy consumption of a system, making it more efficient. Type 3285 is available as a standard ON/OFF or proportional valve, as well as a version with an integrated position controller and a version with an integrated process controller.
