Proportional pressure is used in circulation systems with an extensive pipe system and control valves to generate a variable flow.
Proportional pressure is mostly used in circulation systems with an exten¬sive pipe system and control valves to generate a variable flow.
The pressure loss in the control valves is lower than 50% of the total pressure loss. The differential pressure sensor should be placed at the farthest consumer.
