Description
The Smart Valve Positioner controls valve stroke accurately according to input signal of 4-20mA being input from controller. In addition, highly efficient microprocessing operator built in the product performs various and powerful functions like Auto calibration, PID control, Alarm and Hart protocol.
Tecnical description
- LCD equipped outside of product makes to check the positioner condition in the field directly
- It endures severe vibration
- It is operated normally regardless of change of supply pressure during operation
- Very simple auto calibration method
- Small size
- Reduced ar consumption
- Low voltage (8.5V) operation: support any kind of controller
- Variable orifice is applied: in case of small actuator the hunting is controlled to the optimum condition during operation
- Hart communication makes to process various information of valve and positioner
- Valve system is stable by sending analog feedback signal
- Adjustment of Valve characteristics (Linear, Quick open, Equal percentage) is available
- Specific flow control is available with setting 16 point at users’ command
- Tight Shut-Close and Shut-Open can be set voluntarily
- PID parameters can easily adjusted in the field without additional communicator
- The pressure of Air filter regulator is sent to Actuator directly with using A/M switch
- Split range such as 4-20mA, 12-20mA is available
- Setting Zero and Span as partial section is available by Hand Calibration function.
