Radiators with Differential Pressure Control (DPCV)
Radiator Systems are often seen including a radiator thermostat (TRV) on each radiator. The TRV will open or close depending on setting and surrounding room temperature and allow more or less water into the radiator, but on its own it will not balance the flow and in case of high differential pressure across the TRV, it will screen unbearably.
The DPCV will keep a constant differential pressure, ΔpC, across the circuit it is controlling. This helps the sub-system to maintain a constant differential pressure, keep flow steady and avoid noise. The DPCV’s partner valve can be a simple ball valve, a static flow balancing valve or an automatic balancing valve (ABV). The ultimate solution is the combined DPCV and ABV allowing full pressure and flow control to the zone incl. ON/OFF control for possible night temperature reduction.
FlowCon recommends the following DPCVs and Partner Valves:
