3270 2/2-Way Motor Valve
Brand: Burkert Fluid Control Systems
Type 3270 is a direct-acting and general-purpose motor valve for shut-off, used as regulating unit in control loops.
A linear stepper motor as actuator drives the valve, which comes in a compact and robust housing. The integrated electronics simplify the process integration; additional actuation modules are not necessary.
Due to an elastomeric seat seal the valve closes tight up to the DN specific nominal pressure. In case of power failure, the actual valve position will be kept. If a specific safety position in case of power failure is required, this can be realized by using an external buffer module.
The motor's power consumption in opened or closed position is nearly zero. This key feature can reduce the energy consumption of a plant dramatically and thus make it more efficient.
The LED gives an optical indication of the valve‘s position and status.
