Finally, the pressure drop through the valve, compared to the system it is controlling, have to be correctly designed. Over- or undersized valves will trigger operating problems and lack of control of the system. Air elimination is even more important in a chilled-water system than it's in a hot-water system, as a outcome of cold water holds more air. Without an air separator, the constant air-water combination being pumped will dramatically lower heat transfer capabilities as a end result of…See More
