• FLOWCON FLOW CONTROLS IN AIR CONDITIONING AND HEATING APPLICATION The hydronics system in a building is always in a dynamic state with valves and pumps activating on demand which in turn, causes wide pressure fluctuations. Without pressure compensating flow control valves, circuit closer to the pressure source will rob remote circuits of adequate flow. Similarly, uncontrolled pumps may work against low head, resulting in waste of energy, cavitation and overload. Whether they are used to maintain flow in constant flow systems or to limit maximum flow in variable flow systems, FlowCon Flow Control Valves economically solve these problems.
