or after the valve. Even the most controllable standard (pressure dependent) temperature control valve will allow a change in flow as the differential pressure in the system changes, which is an everyday occurrence. Any time a chilled water or hot water system is operating at less than design maximum load conditions – which is most of the time – differential pressures in the system tend to increase, resulting in overflow through the control valves. This overflow condition results... (read more)
