  • Modulating Feed Water Valves | Products | BoilerWAREhouse

    Modulating Feedwater valves allow for constant incremental adjustments to feed water into your boiler. They come in all types from ball valves, to knife gates, to globe valves and operate off of many types of signals. Some typical applications are 0-135 ohm slide wires from a McDonnell and Miller 7b switch or a 4-20ma signal from a differential

  • Automatic Level Control Systems | Spirax Sarco

    In this type of system the feedpump runs continuously, and an automatic valve (between the feedpump and the boiler) controls the feedwater flowrate to match the steam demand. When operating correctly, modulating control can dramatically smooth the steam flowrate chart and ensure greater water level stability inside the boiler.

    Kelden Feedwater Valve was developed nearly 32 years ago. After many years of searching for a modulating feedwater valve that would shut-off and not "leak thru", we decided to design our own. We currently have several hundred of these valves in high pressure steam applications all over the country and they simply work great.
