Type Description
The direct-acting motor proportional valve Type 3280 serves as a regulating element in various 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 to hold a specific opening position of the valve 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. Type 3280 is available in following versions: - Standard proportional valve - Proportional valve with integrated positioner - Proportional valve with integrated process controller
1）Actuator isolated from flow path
2）Excellent range and fast response times
3）Low power consumption
4）Positioner and process controller versions available
5）Orifice sizes 2 to 10 mm
