Burkert 3281 is a 2-way direct-acting valve driven by a motor. Ideal for dosing gases or liquids in closed or open circuits.
The valve is actuated by a linear stepper motor. The integrated electronic unit simplifies the integration of the valve into the system; no additional actuator modules are required.
The motor does not require energy to maintain a specific valve opening. This feature can significantly reduce the energy consumption of the installation.
Two versions of TYPE 3281 are available:
- with integrated positioner
- with integrated process controller.
Technical specifications:
- Excellent adjustment range
- The drive is not wetted
- Fast response time
- Ambient temperature range: up to 130 °C
- Nominal diameter DN 4 … 10
