System example

Adjustment

Total flow
1. Connect differential pressure instrument to adjustment valve with measuring point.
2. Set the control valve to fully open position (stem depressed, bypass closed).
3. Measure the water until it reaches the calculated value.

Bypass flow
4. Set the control valve to fully closed position (stem up, bypass open).
5. Adjust the inner adjustment valve until the outer adjustment valve achieves the same pressure drop as before.
