Parameter | Description
P-Gain | The P-Gain is the proportional factor of the fixed control algorithm. A higher P-Gain results in faster response, higher over- / undershoot of pressure.
I-Gain | The I-Gain is the integral factor. The I-Gain helps to reach the target pressure exactly.
Direction | The Control Direction defines the type of application, if the valve is mounted in downstream or upstream. Downstream means the valve is after the chamber and before the pump. Upstream, valve is mounted before chamber and pump.
