Modulating feedwater valves, such as WARE Mod-V, were developed to answer the industry’s need for greater control, efficiency, and performance in larger boiler systems. They’re recognized as smart solutions that are showing up in more and more systems, and for good reason. With properly modulated feedwater, a boiler can operate with better efficiency and be able to respond to shifts in demand without appreciable lag. That can be a game-changer.
To keep a boiler system operating at optimal efficiency, it needs enough water to do its job. However, the definition of “enough” changes throughout the day as demand for steam increases and decreases. This is called “load swing,” and different boiler systems use different methods to compensate for it. More and more, the flow of supply water is being controlled through the use of modulating feed valves, and there are a lot of reasons why.
