One Pipe Steam
Valve |
|
 |
|
Operation The Macon one-pipe
steam valve assembly consists of the reliable B26000 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. |
|
Important: |
1 |
Installing the Macon one-pipe steam valve assembly does not
eliminate other controls in the system. The boiler must be cycled in some
manner. |
2 |
If the boiler is cycled from a space thermostat in one
zone, do not apply a radiator valve to that zone's radiation. |
3 |
Do not apply a radiator valve in a one-pipe steam system
that does not use steam air vents venting to the atmosphere on each radiation
unit. |

Vacuum break is required for proper operation. |
