3275 2/2-Way Motor Valve
Brand: Burkert Fluid Control Systems
Type 3275 is a direct-acting and general-purpose motor valve for shut-off, used as regulating unit in control loops. A stepper motor as actuator drives the valve which is incorporated in a compact and robust housing.
The integrated electronics simplify the process integration; additional actuation modules are not necessary.
The drive shaft shifts a very smooth ceramic disc over a second fixed ceramic disc. The fixed ceramic disc is simultaneously the valve seat. By turning the ceramic disc the valve opens. The seat tightness is achieved by the very smooth surface of the stacked ceramic discs.
In case of power failure the actual valve position will be kept. Therefore, this valve is not suitable as safety shut-off valve. 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.
