Differential pressure regulators are built into the system where a constant differential pressure is desired.
Differential pressure regulators are built into the system where a constant differential pressure is desired. They are often installed at the connection point between a district heating system and a consumer building. This ensures that there is a constant differential pressure available for the building’s heating system.
This protects the building’s installation against the differential pressure variations that arise in the district heating distribution network and thus makes it possible to perform an accurate dimensioning of the heating system.
Differential pressure regulators can also be mounted so they create a constant differential pressure across regulating valves. In this way, a valve authority of 100 % for the regulating valve can be achieved, as it is independent from the pressure relationships in the rest of the system. This ensures optimal regulation of the unit relying on the valve. A mixing loop is an example such a unit.
