Pressure-Independent Control Valve - Logotherm LogoCool S-Line Technische Information Für Montage Und Betrieb

4.2 Pressure-independent control valve

Flow rate controller: Ballorex Dynamic depending on unit,
S-Line LogoCool 1-5 kW
S-Line LogoCool 2-12 kW
S-Line LogoCool 5-16 kW
M-Line LogoCool 9-24 kW
The Ballorex Dynamic valve is a combination of a pressure-independent flow rate limiter and
a control valve that maintains a constant flow irrespective of any fluctuations in pressure. The
valve combines an automatic flow rate limiter and a two-way control valve.
Design
To set the primary flow speed, remove the servomotor (incl. adapter) and replace it with the red
cap (included in the scope of supply of the device) as illustrated.
