Characterised 20mm 3 port valve Kvs 6.3 Suitable Actuators LR../LRF.. – R3020-6P3-S2

Media:                                               Cold and warm water, water with glycol up to max. 50% vol.
Medium Temperature:                     -10…120°C
Medium Temperature Note:           The allowed media temperature can be limited, depending on the type of actuator. Limitations can be found in the respective data sheets of the actuators.
Rated Pressure ps:                         1600 kPa
Closing Pressure ∆ps:                    1400 kPa
Differential Pressure ∆pmax:         350 kPa
Differential Pressure Note:             200 kPa for low-noise operation.
Flow Rate:                                         Bypass B – AB: 70% of kvs value
Flow Characteristic:                         Control path A – AB: equal percentage (VDI/VDE 2178), optimised in the opening range, Bypass B – AB: linear (VDI/VDE 2178).
Leakage Rate:                                   Control path A – AB: Leakage rate A, air-bubble tight (EN 12266-1), Bypass B – AB: Leakage class I (EN 1349 and EN 60534-4) approx. 1…2% of the kvs value, with respect to the largest value within the DN.
Pipe Connectors:                              Internal thread according to ISO 7-1
The angle of Rotation:                      90° (Operating range control path A – AB 15…90°, Bypass B – AB 15…70°)
