burkert 3270電動閥 Type 3270 is a direct-acting and general purpose motor valve for shut-off, used as regulating unit in control loops. burkert 3270電動閥 A linear stepper motor as actuator drives the valve, which comes in a compact and robust housing. Analogue input signals are processed by the integrated control electronics. Due to an elastomeric seat seal the valve closes tight up to the DN specifi c nominal pressure (see ordering chart on p. 4). In case of power failure, the actual valve position will be kept. The motor’s power consumption in opened or closed position is nearly zero. Only during valve switching does the motor need power. This key feature can reduce the energy consumption of a plant dramatically and thus make it more effi cient.
