The Macon one-pipe steam valve assembly consists of the reliable EVO direct mounting thermostat. The thermostatic head contains a temperature sensitive wax which expands and contracts on a rise and fall of temperature in the sensed area. When the temperature rises above the temperature selected, pressure from the expanding wax closes the valve, preventing or restricting the flow of steam through the radiation unit. When the room temperature drops below the selected temperature, the valve opens and allows an increase of steam flow through the radiation unit. This modulating process continues automatically to maintain the temperature you selected. The OPSK controls room temperature by regulating the amount of air and steam in the radiator.
