of the heating system
Applications: Suitable for systems that can operate with significant flow rate variations, such as those using thermostatic radiator valves or motorized zone valves. The bypass allows for recirculation proportional to the number of valves closing: this limits the maximum differential pressure generated by the circulator, ensuring that it does not deviate from the performance selected during the design phase, under all operating conditions.
Heat pump systems. In these circuits, it is advisable to always ensure a small flow in the circuit even when all the utilities are closed, to allow the energy producer to operate in a balanced and economical manner, without repeated stops and starts. The bypass differential valve allows for recirculation that maintains the minimum necessary circulation.
