1) | 3-port valve used as a diverting valve (AB→A, AB→B). |
2) | 3-port valve used as a mixing valve (A→AB, B→AB). |
Kvs | Nominal flow rate for cold water (5…30 °C) through the fully open valve (H100), at differential pressure 100 kPa (1 bar). |
∆Pmax | Max. permissible differential pressure across the valve’s control path, valid for the entire actuating range of the motorized valve (max. recommended operating differential pressure). |
∆Ps | Max. permissible differential pressure at which the motorized valve closes securely against pressure (close off pressure). |
