NettetWhen sizing a control valve, the rule of thumb is to size it so that it operates somewhere between 20-80% open at maximum required flow rate and whenever possible, not much less than 20% open at the minimum required flow rate. The idea is to use as much of the valve’s control range as possible while maintaining a reasonable, but not excessive ... NettetCheck whether the positioner output is connected to valve actuator. To begin calibration the operation, need to supply 4 milliamps to set the zero position. Supply 20 milliamps and using the flapper adjust the span. Check zero when span adjustment is finished and repeat the process until we have the correct travel.
