Proportional pressure is used in circulation systems with a pipe system with low pressure loss and control valves to generate a variable flow.
The illustrations show that the pressure drop in the control valves is lower than 50 % of the total pressure drop.
- Illustration one shows a heating system with 2-way valves
- Illustration two shows an air-conditioning system with 2-way valves
Grundfos circulator pumps and water transfer pumps ensure proportional pressure flow in domestic and commercial buildings and air conditioning applications.
