  • Steam Mixing Valves

    For Use With: Water, Steam. Max. Inlet Temperature: 240° F. Max. Inlet Pressure: 80 psi. Mix steam and cold water to reach your set outlet temperature more quickly than valves that only mix hot and cold water. Adjust the outlet temperature within the range. This valve has internal check valves with strainers to prevent backflow and trap debris.

  • Aquastat on a steam boiler — Heating Help: The Wall

    2022-1-2u2002·u2002The aquastat is controlling the temperature of the hot water -- not the steam (that is controlled by a pressure controller on the boiler -- which should be set to no more than 1.5 psi). If this is a hot water coil in the boiler itself (that is, no indirect tank) you need to have a mixing valve on the hot water output, to avoid scalding people.
