Pressure Control Speed adjustment

Valve speed effects: Response time

 

Adjustment range is from 0.001 to 1.0

Default value is 1.0
 

This parameter effects valve plate actuating speed.

Speed adjustment is effective for PRESSURE CONTROL and POSITION CONTROL.

 


Pfeil

Normally best pressure control response is achieved with maximum Pressure Control Speed. In particular applications it may be of advantage to have a slower valve response.

OPEN and CLOSE are always done with maximum speed.

 

Adjustment procedure:

 

1.Use optimal Gain Factor, sensor delay time and setpoint ramp according to preceding tuning steps.

2.Open valve.

3.Control a typical pressure / flow situation.

4.Repeat from step 2 with slower Pressure Control Speed until required response is achieved.
